Branching out: A simple and inexpensive cobalt/triarylphosphine catalyst promotes aldimine-directed hydroarylation of styrene with high branched regioselectivity to afford 1,1-diarylethane derivatives in good yields under mild reaction conditions. The ortho-formyl group in the hydroarylation products is amenable to dehydrative cyclization, to give fused polycyclic aromatic hydrocarbons, as well as decarbonylative removal.
