The reaction of benzimidazole with phenylacetylene, ethyl propiolate, and their β-bromo derivatives leads to the corresponding β-substituted N-vinylbenzimidazoles.

Abstract3-Formylindazoles are converted to 1-methyl- and 2-methyl-substitutedβ-(3-indazolyl)acrylic andα-bromoacrylic acids by the Wittig reaction. Dehydrohalogenation of theβ-(3-indazolyl)-α-bromoacrylic acid esters gaveβ-(3-indazolyl)propiolic acids, the decarboxylation of which gives isomeric 1-methyl- and 2-methyl-substituted 3-ethynylindazoles.

Abstract2-Alkynylbenzimidazoles were obtained by alkylation of 2-benzimidazolylacetylenes with alkyl halides in liquid ammonia in the presence of sodium metal. The strong — I effect of the 2-benzimidazolyl group hindered attack of electrophilic reagents in alkylation and hydration reactions of 2-benzimidazolylacetylenes. Condensation of 2-ethynylbenzimidazoles with bromophenylacetylene under the conditions of the Cadiot-Chodkiewicz reaction gives unsymmetrical diynes.
