The heterocyclization of unsaturated nitriles and ethyne catalyzed by cyclopentadienyl‐1,5‐ cis , cis ‐cyclooctadiene‐cobalt(I) and promoted by light has been studied in toluene as solvent. Acrylonitrile and substituted acrylonitriles gave results of interest in the preparation of 2‐vinylpyridines. No reaction could be observed using fumaronitrile, maleonitrile or allyl cyanide. The ( E )/( Z )‐ratio of educts and products seems to be not influenced by conditions in the reaction.
