45 - 084Electrochemical Vinylation of Aryl and Vinyl Halides with AcrylateEsters Catalyzed by Cobalt Bromide. — Electrolysis of aryl halides(I) in the presence of acryl ester (II) using a sacrificial Fe-anode permits aCoBr2/bipy-catalyzed Heck reaction yielding E-olefins (III) stereoselectively.However, significant amounts of the addition products (IV) are also isolated.— (GOMES, PAULO; GOSMINI, CORINNE; NEDELEC, JEAN-YVES;PERICHON, JACQUES; Tetrahedron Lett. 43 (2002) 34, 5901-5903; Lab.Electrochim., Catal.
