AbstractWhen the title compounds are thermolyzed in the gas phase under vacuum or in hot quinoline, several products are formed. A predominant product in all cases is a chlorine-free buta-1,3-diene which has been formed by formal debromochlorination, a reaction not previously observed during thermolysis of chlorinated bromocyclopropanes.

摘要当标题化合物在真空中或在热喹啉中在气相中热分解时,形成几种产物。在所有情况下,主要的产物是无氯的1,3-丁二烯,它是通过正式的脱溴氯化反应形成的,该反应以前在氯化溴代环丙烷的热解过程中没有观察到。 图形概要
