Abstract

N,N,O-donating ligand was prepared from the condensation of 2- amino benzothiazole with various aromatic aldehyde. Metal complex of this ligand is neither air nor moisture sensitive. The effects of varying solvents, bases, and ligand/copper ratio on the performance of the coupling reaction were investigated. This method is a very simple, efficient and mild protocol for the cross-coupling of aryl bromides with arylboronic acids, and the reactions proceeded effortlessly in excellent yields within short reaction times. All reactions are carried out in anhydrous condition.
