Abstract

The dichloro-and dibromocarbene adducts of chloroprene and 2, 3-dichlorobutadiene are readily dehalogenated by reaction with methyllithium to give 1-halo-2-vinylcyclopropenes which on further lithium-halogen exchange give synthetically useful 1-lithio-2- vinylcyclopropenes. Trapping of 1-lithio-2-(1-chlorovinyl) cyclopropene with methyl chloroformate leads to a very unusual cyclononadienyne.
