Abstract
Abstract When 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.
