Styrene is a convenient and cheap oxidant in transfer hydrogenations. The reduced product ethylbenzene can be removed by simple distillation.
[Ir(Cp*)Cl2]2 catalyzes the rearrangement of oximes to furnish amides. An iridium-catalyzed transfer hydrogenation between alcohols and styrene and the subsequent formation of an oxime allows the conversion of alcohols into amides in a one-pot process.
