摘要：

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. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
