摘要
Addition-elimination reactions of an arylaluminum reagent with vinylarenes is achieved mediated by a rhodium catalyst. The reaction of dimethyl(phenyl)aluminum with a rhodium(I) catalyst takes place to afford (E)-stilbene. The reaction is promoted by the addition of ketone as an additive to give (E)-stilbene in a quantitative yield. A nickel complex bearing cyclopentadienyl (Cp) and N-heterocyclic carbene (NHC) ligands also catalyzes the reaction to afford 1,2-diarylethenes accompanied by a small amount of the saturated byproduct, 1,2-diarylethanes.
