Exploration of the mechanism and scope of the CuI/DABCO catalysed CS coupling reaction

Abstract A cost effective and easily available CuI/DABCO catalytic system has been developed for the C S cross-coupling reaction. This method is extremely useful for the thioetherification of aryl and heteroaryl halides, providing excellent yields and good chemoselectivity. We have also explored the mechanism of the reaction using DFT studies.
