ResumoThe reaction of aromatic or aliphatic C-H bonds with terminal alkynes gives 1,1-disubstituted ethenes when photocatalyzed by RhCl(CO)[P(CH3)3]2 under mild conditions. The activation of the C-H bonds of n-hexane occurs regioselectively at the methyl group leading to the formation of 2-phenyl-1-octene in the presence of phenylacetylene. The reaction of benzene with 1-phenylpropyne under carbon monoxide affords cis- and trans-3,4-diphenyl-3-buten-2-one.
