The classical methods for the synthesis of alkynes involve the alkynylation of alkyl halides with metal acetylides1 as well as the base-promoted dehydrohalogenation2 of vicinal dihalide/vinyl halide. Our research interest is directed toward the synthesis of 1, 2- cyclopropyl-and/or cyclobutylalkynes which can be achieved either by generation of the acetylene bond from an appropriate precursor with dicycloalkyl substituents or by the ...
