Rhodium(III)-Catalyzed Direct Coupling of Arylphosphine Derivatives with Heterobicyclic Alkenes: A Concise Route to Biarylphosphines and Dibenzophosphole Derivatives
The redox-neutral direct coupling of arylphosphine oxides with heterobicyclic alkenes proceeds smoothly under rhodium(III) catalysis involving hydroarylation followed by dehydrative aromatization to form biarylphosphine oxides. Related phenylphosphinic and phenylphosphonic esters as well as phenylphosphine sulfides also undergo ortho-arylative coupling. Furthermore, phenylphosphinothioic amides can
