Environmentally benign approach towards C-S cross-coupling reaction by organo-copper(II) complex.

Abstract

C-S cross-coupling reaction in water giving an excellent yield of the desired C-S coupled product by using a newly developed Bis[2-(4,5-diphenyl-1H-imidazol-2-yl)-4-nitrophenolato] copper(II) dehydrate complex as catalyst. Although it was the first report of the synthesis of such a novel organo-copper complex from our laboratory, its potential catalytic application was not tested so far. Keeping this in mind and based on our anticipation, we developed a greener route for the C-S coupling reaction. The result is very interesting and comprises the subject matter of this report.
