of a photomediator such as benzophenone, alkynes with electron-withdrawing groups react with cycloalkanes to give vinyl cycloalkanes. The reaction involves the regiospecific addition of a photochemically generated cycloalkyl radical to the beta-carbon of the alkyne. The stereochemical outcome of the reaction depends on the nature of the photomediator and alkyne used.

Heck-type coupling of inactivated alkylhalides and alkenes, catalyzed by amorphous CuB23 alloy short nanotubes, has been developed. Such couplings occur on the surfaces of nanotubes via a single-electron oxidative reaction. The results indicate that CuB23 nanotubes are efficient catalysts to replace Pd and Ni complexes for such Heck-type coupling.
