[Zn(L-Pro)2] as a Simple and Efficient Catalyst: A Convenient Route for the Synthesis of Thia-Michael Derivatives via Green Chemical Approach

摘要

A simple and convenient route for the synthesis of thia-Michael products was established using pyrazol-5(4H)-one with various thiophenols in the presence of [Zn(L-Pro)2],an efficient catalyst under mild reaction conditions. The salient features of this methodology are good yields, eco-friendly catalyst, low catalyst loading and faster reaction times.
