The reaction of 2-Alkyl-1,1-dichlorocyclopropanes with lithium naphthalene

Abstract

2-Alkyl-1,1-dichlorocyclopropanes react with lithium naphthalene to give a mixture of dechlorinated alkylcyclopropanes and unsaturated hydrocarbons. For example, a mixture of octylcyclopropane and undec-1-yne was obtained from the reaction of 1,1-dichloro-2-octylcyclopropane and lithium naphthalene.
