Reversible Heterolysis of H2 Mediated by an M−S(Thiolate) Bond (M = Ir, Rh): A Mechanistic Implication for [NiFe] Hydrogenase
摘要:
Facile H-2 heterolysis was found to be mediated by coordinatively unsaturated Cp*Ir and Cp*Rh thiolate complexes. The reaction of iridium complex is reversible, and the formation of an intermediary Ir-H/thiol complex was detected. The reversible conversion between thiolate complex+H-2 and hydride complex+thiol provides an intriguing functional model of [NiFe] hydrogenase.
