Abstract
Dichlorocyclopropane compounds, prepared from olefins or unsaturated carboxylic acids with chloroform, react with lithium naphthalenide to give alkylcyclopropanes, and/or unsaturated compounds as dechlorinated products. For example, a mixture of octylcyclopropane and 1-undecyne was obtained from the reaction of 1, 1-dichloro-2-octylcyclopropane and lithium naphthalenide. 9, 10-Nonadecadienoic acid was obtained as a main product from the reaction of 9, 10- (dichloromethylene) octadecanoic acid and lithium naphthalenide.
