We herein report several highly active catalyst systems with thiadiazolidine 1-oxides as ligands for palladium in the Mizoroki–Heck reaction. Excellent yields of stilbenes derived from aryl iodides and bromides have been achieved using as little as 0.00002 mol % catalyst. The ligand/palladium system can be stored as a stock solution open to air at room temperature with no observable loss of activity
我们在此报告了几种高活性催化剂体系,其中噻二唑烷1-氧化物作为Mizoroki-Heck反应中钯的配体。使用低至0.00002 mol%的催化剂已获得了源自芳基碘化物和溴化物的斯蒂尔苯的优良收率。配体/钯系统可以在室温下以对空气开放的储液形式存储,几个月内没有可观察到的活性损失。
