Synthesis of 8,9-Disubstituted Fluoranthenes by Domino Two-Fold Heck/Electro-cyclization/Dehydrogenation of 1,2-Dibromoacenaphthylene. — A simple proce-dure is developed for the preparation of the title compounds as synthons of higher--membered polycyclic hydrocarbons. Generally, somewhat higher yields are obtained with acrylates than with styrenes. — (ULLAH, I.; NAWAZ, M.; VILLINGER, A.; LANGER*, P.; Tetrahedron Lett. 52 (2011) 16, 1888-1890, http://dx.doi.org/10.1016/j.tetlet.2011.02.032 ; Inst.
