Abstract
The dichloro- and dibromocarbene adducts of chloroprene and 2,3-dichlo robutadiene are readily dehalogenated by reaction with methylithium to give 1-halo-2-vinylcyclopropenes which on further lithium-halogen exc hange give synthetically useful 1-lithio-2-vinylcyclopropenes. Trappin g of 1-lithio-2-(1-chlorovinyl)cyclopropene with methyl chloroformate leads to a very unusual cyclononadienyne. Copyright (C) 1996 Elsevier Science Ltd
