Reduction with Samarium(0). Debromination of vic-Dibromides to Alkenes

Article abstract of DOI:10.1246/cl.1994.1279

Three electrons from Sm(0) to Sm(III) can be available during the title reduction which was achieved in 90-95percent yield with vic-dibromides such as trans-10,11-dibromodibenzosuberone, meso- and dl-1,2-dibromo-1,2-diphenylethane, ethyl 2,3-dibromo-3-phenylpropionate, 2,3-dibromo-3-phenylpropionic acid, and cholesterol dibromide.These reductions were accelerated with a catalytic amount of acid.
