Abstract
Benzoins are simply oxidized to benzils in excellent yields with a catalytic amount of triarylstibanes under an aerobic condition. This catalytic oxidation is heteroatom-specific in the antimony compound and no reaction take place with other group 15 reagents such as triphenylphosphane,-arsane and-bismuthane. The reaction should involve an oxidation– reduction cycle between stibane Sb (III) and stiborane Sb (V) under air.
