General and Convenient Route to Alkenylidenecyclopropanes: Generation of Alkenylidenecarbenes from 1,1-Dibromocyclopropanes under Phase-transfer Conditions

Alkenylidenecyclopropanes have been prepared in a stereospecific manner by the reaction of 1,1-disubstituted 2,2-dibromocyclopropanes with sodium hydroxide under phase-transfer conditions in the presence of alkenes.
