Rhodium-Catalyzed Cross-Coupling of Vinylarenes with Arylaluminum Reagents in the Presence of Ketones

10.1002/ejoc.201301757

The study presents a rhodium-catalyzed cross-coupling reaction between vinylarenes and arylaluminum reagents, which results in the formation of stilbene derivatives, π-conjugated organic materials of interest in organic synthesis. Key chemicals used include diethyl(phenyl)aluminum as the arylaluminum reagent, styrene as a representative vinylarene, and various ketones such as diisopropyl ketone, acetone, and pinacolone, which serve as additives that promote the reaction. The study also explores the use of different rhodium catalysts, including [RhCl(cod)]2, [Rh(OH)(cod)]2, and [Rh(OMe)(cod)]2, to optimize the reaction conditions and yield of stilbene products. The purpose of these chemicals is to facilitate an addition/elimination-type reaction that expands the scope of organic synthesis using organoaluminum reagents, which are known for their functional-group tolerance compared to other nucleophiles like organomagnesium and organolithium reagents.
