A question of nobility : A biomimetic nickel thiolate complex (see scheme; TEA=triethylamine) exhibits unprecedented activity for the title reaction. By using a low concentration of a sacrificial donor, the system maintains significant activity for at least 60 hours. The enhanced stability of the system is ascribed to the ability to proceed through an oxidative quenching pathway.
