摘要

Abstract 1, 1, 2-Trihalocyclopropanes (halogen= chlorine or bromine) undergo 1, 2- dehalogenation on reaction with methyl lithium, and in a number of cases the product is a 1- halocyclopropene. In the reactions of (20, X= Br, Cl) and (25) a rearrangement occurs even at low temperatures and propargylic halides are isolated, while (16) is converted to 2- chlorocyclohex-2-enylidene which may be trapped by furan.
