摘要：

Treatment of gem-dibromocyclopropanes with trialkylmanganate, derived from manganese(II) chloride and three equivalents of Grignard reagent or alkyllithium, followed by an addition of electrophiles provided dialkylated cyclopropanes in good yields. It was found the reaction with alkylmapnesium halide proceeded in the presence of a catalytic amount of manganese(II) chloride. Copyright (C) 1996 Elsevier Science Ltd
