摘要

Two N3O2 pentadentate ligands, BMPP and BPPP, were prepared for synthesizing highly efficient nickel catalysts, [Ni(BMPP)(CH 3CN)](ClO4)2 (1) and [Ni(BPPP)(CH 3CN)](BPh4)(ClO4) (2), for thia-Michael addition of thiophenols to α,β-enones. X-ray structures of 1 and 2 revealed that a labile CH3CN molecule was bound to the nickel center of the catalysts. ESI-MS spectroscopy indicated that thiolate replaced the bound CH3CN molecule and coordinated to the nickel center during the catalytic cycle.
