Cobalt-catalyzed intermolecular stereoselective bisbenzylation of alkynes
摘要:
CoBr2/P(OMe)Ph-2 is found to be an effective catalyst-system for intermolecular bisbenzylation of allcynes with various benzyl bromides in the presence of manganese reductant. The transformation can be carried out under mild conditions, giving rise to stereocontrolled cis-1,2-bisbenzylated alkenes in good yields. (C) 2015 Published by Elsevier Ltd.
