1-Chloro-1-(trichlorovinyl)cyclopropanes 3, prepared from olefins 1 and tetrachlorocyclopropene (2), readily react with 2 equivalents of n-butyllithium (methyllithium) to yield - via 1-chloro-1-(chloroethynyl)cyclopropanes 5 - lithium cyclopropylacetylide

The perchlorovinylcarbene adducts of ethylene and propylene served as precursors to a wide spectrum of 1'-substituted cyclopropylacetylenes 4, 8 and 9, which are versatile polyfunctional molecules.E.g., the acetylenic ester 4c underwent cycloaddition to 1,3-dienes giving otherwise unaccessible compounds.
