Research Interest:
Since July 2007, SKM started his independent carrier as an Assistant Professor at the Indian
Institute of Science Education and Research (IISER)-Kolkata. His approach to scientific research is
multidisciplinary. SKM is currently working on the development of catalysts for a number of very
important homogeneous transformations such as hydroamination reaction, Suzuki coupling, Ullmann
coupling, ring opening polymerization, and Sonogashira reaction. His group is now engaged in
designing catalysts derived from green and rather inexpensive main group elements, in addition to
transition etals PI’s group is working for the develop ent of nano atalysts based on single walled
5
carbon nanotubes and graphene oxide aiming at synthesis of compounds having medicinal
importance. Additionally, SKM is working for the development of copper based anti-cancer drugs .
SKM’s group has re ently pioneered the design and develop ent of aterials potential for next
generation storage device which works based on the spin of the electron. The special class of
ole ule designed at SKM’s group an hold the free electron on injection from a ferromagnetic
substrate and the spin state of the electron can be switched back and forth using the magnetic field as
an external stimuli resulting in a magnetoresistance of 20% near room temperature. This findings
demonstrate a molecular platform to develop storage element or a 'bit where the binary states of '0' or
'1' are represented by the electron spin state in the molecule – 'spin-up' or 'spin down'. This finding
can potentially lead to scalable molecular memory devices of next generation with superior storage
apa ity with 1000 ti es stronger storage ablity than today’s best storage device.

Project # 1
1. A. Principal Investigator : Swadhin K Mandal
B. Project Title: Design and Synthesis of Heterometallic Catalysts: Olefin Polymerization,
Copolymerization and Tandem Catalysis
C. Status: Completed (30th
April, 2012) D. Duration: 36 months (April 2009 to April 2012) E. Total Cost: Rs. 19,44,000
F. Funding Agency DST (SR/FT/CS-020/2008)
G, H and I. Summary, Highlights and Major Results:
The major new observations of the project have been three fold:
a. Development of nontoxic catalysts was accomplished for ring opening polymerization
leading to biocompatible and biodegradable cyclic polyesters using aluminum based
catalyst as well as abnormal N-heterocyclic carbene based organocatalyst.
b. Calcium and zirconium based heterobimetallic catalyst was developed which showed for
the first time dual catalytic activity in the C-N bond forming intramolecular
hydroamination reaction.
c. Abnormal N-heterocyclic carbene based palladium catalysts were developed for Suzuki
coupling of inactive and relatively cheap aryl chloride substrates showing room
temperature activation with quantitative yield of the product under very low catalyst
loading. These catalysts are among the best known catalysts for the Suzuki-Miyuara
coupling of aryl chloride substrates.
Publication: 13 publications
Project # 2
A. Principal Investigator: Swadhin K Mandal
B. Project Title: Syntheses and Design of Green Catalysts for Hydroamination Reactions
Based on Phenalenyl Ligands.
C. Status: Ongoing D. Duration: 36 months (July 2010 to July 2013) E. Total Cost: Rs. 12,80,000 F. Funding Agency CSIR (01(2369)/10/EMR-II)
Highlights and Major Results:
We accomplished the synthesis and characterization of organozinc complexes bearing
symmetrical phenalenyl (PLY) based N,N-ligands. Reactions of phenalenyl based ligands with
ZnMe2 led to the formation of organozinc complexes [N(Me),N(Me)-PLY]ZnMe and
17
[N(iPr),N(
iPr)-PLY]ZnMe under evolution of methane. Organozinc complexes were
characterized by NMR spectroscopy and elemental analysis and X-ray crystallography.
Preliminary investigation of complexes for intramolecular hydroamination of unactivated
primary aminoalkenes revealed that these complexes function as active catalysts. More detailed
study to understand the catalytic process is currently underway.
Publication: 4 publications and several in process

Major Research Highlights at IISER-Kolkata (in SKM’s Group)
Since July 2007, the SKM is working in the development of catalysts for a number of very
important homogeneous transformations such as hydroamination reaction, Suzuki Coupling,
Ullmann coupling, ring opening polymerization,and Sonogashira reaction. SKM’s approa h to the
development of catalysts involves both homogeneous and heterogeneous catalysis using main group
based catalysts and transition metals based catalysts. A brief description of recent activities of
SKM’s resear h in atalyst develop ent at IISER-Kolkata is summarized below.
A. Development of Dual Catalyst for Hydroamination Reaction:
26
SKM’s group has re ently designed a al iu based heterobi etalli atalyst with a Zr-O-Ca
linkage which acts as a dual catalyst for activation of primary and secondary aminoalkenes
(Mukherjee et. al. Angew. Chem. Int. Ed. 2011, 50, 3968–3972 and RSC Advances, 2013, 3,
1255–1264.). In this work, it was shown that a Group 4 metal can be fixed on a Group 2 metal
through an oxygen-bridge to carry out intramolecular hydroamination of primary and secondary
aminoalkenes and the concept of dual catalyst has been accomplished for the first time in the area
of hydroamination catalysis. Preliminary investigation indicates that the calcium center activates
the primary aminoalkenes and the zirconium center activates the secondary aminoalkenes
(Scheme 1).

calcium based heterobimetallic catalyst.
Future Implication of this work:
This work opens up the possibility of using calcium based dual asymmetric catalyst for
hydroamination process using chiral ligands.

nonbonding orbital. Later, the concept of using this nonbonding orbital of phenalenyl for
designing neutral free radical based molecular conductors was introduced (Nature 1975, 256,
394). Now nearly after half a century of HMO calculations on phenalenyl system, SKM’s group
postulates and establishes that the presence of this readily available nonbonding orbital in the
phenalenyl system can be utilized as noninnocent ligand to influence the catalytic outcome
(Scheme 2, Sen et. al. Chem. Eur. J. 2012, 18, 54–58, Mukherjee et. al. Chem. Eur. J. 2012, 18,
10530-10545 and Sen et. al. Dalton Trans. 2013, 42, 1893-1904.).
Scheme 2. The accessible nonbonding orbital on phenalenyl ligand acts as electron acceptor and
thus tunes the HOMO – LUMO energy gap between lactide monomer and catalyst in ring
opening polymerization which in turn results in modulating the catalytic activity of
organoaluminum complexes.
Future prospects of this result in molecular spintronics: This work represents a major step
forward in phenalenyl chemistry, dealing with cationic phenalenyl states to design molecular
catalysts using its electron acceptance capability. Very recently, SKM’s group designed and
shown that the cationic state of phenalenyl unit when created with zinc metal coordination can be
used as non-innocent building block for construction of spin memory device (Scheme 3, Nature,

2013, 493, 509–513). The study reveals that when a non-magnetic and non-conducting
organozinc phenalenyl compound is deposited over a ferromagnetic substrate, it accepts electron
from the substrate and becomes magnetic and conducting. The external spin injection to the
organozinc phenalenyl compounds takes place from the ferromagnetic cobalt to the empty
nonbonding orbital of phenalenyl unit in the cationic state. Interestingly, the spin state of the
electron can be switched back and forth using the magnetic field as an external stimuli resulting
in a magnetoresistance of 20% near room temperature. This phenomena of the cationic
phenalenyl moiety of the organozinc phenalenyl compound demonstrates a molecular platform
for creation of storage element or a 'bit' where the binary states of '0' or '1' are represented by the
electron spin state in the molecule – 'spin-up' or 'spin down'.This type of phenalenyl based
molecules could provide a platform for developing molecular memory devices of next generation
with superior strength whi h is based on th e phenalenyl’s ability to a ept and anipulate the
spin of the electron.
D. New Face of N-Heterocyclic Carbene:
The application of metal-carbene compounds in organic synthesis has been recognized since
last two decades. In 2009, Bertrand and co-workers (Science 2009, 326, 556–559) isolated a
new class of carbene named abnormal N-heterocyclic carbene (aNHC) in which the carbene

center is no longer located between the two nitrogen atoms but is generated between nitrogen
and carbon atoms (also see Science, 2009, 326, 532–533). SKM’s group has established the
first application of the aNHC in ho ogeneous atalysis SKM’s group has shown for the first
time that an aNHC can be used very efficiently in metal free ring opening polymerization of
three different cyclic esters leading to the development of best organocatalyst among any
NHCs reported till todate (Sen et al. Chem. Commun. 2011, 47, 11972–11974, Scheme 4).
Scheme 4. The first report of aNHC as catalysts in any organic transformation in this case it is
ring opening polymerization reaction which undergoes through a series of nucleophilic attack.
Also SKM’s group has used aNHC to synthesize halobridged palladium dimers for Suzuki–
Miyaura cross coupling of unreactive aryl chloride substrates leading to the development of one
of the best known catalysts for aryl chloride activation at room temperature under Suzuki–

Miyaura cross coupling condition (Scheme 5, Sau et al. Chem. Commun. 2012, 48, 555–557).
Future Prospects of this Result: This result is in particular very stimulating for further research
to use aNHC as new breed of NHC ligands for application in homogenous catalysis which
largely remained unexplored so far. Given the fact that aNHC is more basic than its normal NHC
counterpart it will be expected to behave as more stronger -donor to hold the metal center more
strongly. This will reduce the possibility of leaching in catalytic condition, Thus it will not be
surprising to witness a new era of aNHC based catalyst development to come up in future. The
current project also deals with the main group chemistry (Group 14) of the aNHC and its
application in CO2 activation.
Scheme 5. The aNHC palladium dimers exhibited room temperature activation of aryl chloride
substrates and the catalyst remained live upto 10 consecutive cycles.

SKM’s group is now a tively involved in the develop ent of supported heterogeneous palladium
nanocatalyst for C-C bond formation targeting at the one pot multicomponent synthesis of
important drug molecules with good recycling efficiency. The development of palladium catalyst
for C-C bond formation and its immense economic value in pharmaceutical industries has already
been re ognized with the award of Nobel Prize in 2010 SKM’s group established one-pot
multicomponent synthesis of pharmaceutically important 2,4-disubstituted pyrimidines and a
tetrahydro-β-carboline derivative using supported palladium nanoparticles utilizing copper free
acyl Sonogashira reaction protocol (Scheme 6, Santra et al. Green Chem. 2011, 13, 3238–3247
