摘要

The air-stable complex Pd (η3-allyl)(DTBNpP) Cl (DTBNpP= di (tert-butyl) neopentylphosphine) serves as a highly efficient precatalyst for the arylation of amines and enolates using aryl bromides and chlorides under mild conditions with yields ranging from 74% to 98%. Amination reactions of aryl bromides were carried out using 1− 2 mol% Pd (η3- allyl)(DTBNpP) Cl at 23− 50° C without the need to exclude oxygen or moisture. The C− N ...
