摘要

Preparation of alkenes via a manganate-induced alkylation–elimination sequence was investigated. The reaction of 2-alkoxy-1, 1-dibromoalkanes with trialkylmanganates afforded disubstituted or trisubstituted alkenes. Treatment of 2-alkoxy-1, 1, 1-tribromoalkanes with trialkylmanganates provided trisubstituted or tetrasubstituted alkenes through bromine– metal exchange, transfer of two alkyl groups from manganese to carbon, and successive ...
