A Bioinspired ZnII/FeIII Heterobimetallic Catalyst for Thia-Michael Addition
摘要:
A novel tetranuclear Zn-II/Fe-III heterobimetallic complex was synthesized, and the complex can efficiently catalyze the Michael addition of thiophenols to alpha,beta-unsaturated enones, even for tertiary carbon sulfur bond formation.
A convenient Fe(OTf)2-catalyzed Michael additionreaction of thiols to α,β-unsaturated carbonyl compounds was developed. The use of a simple procedure (EtOH, room temperature, air atmosphere) allowed to set up effective green catalytic conditions for the C–S bond formation. The scope of the reaction was demonstrated using various substituted thiols and original Michael acceptors. The corresponding
