Abstract

A palladium/imidazolium chloride system has been used to mediate the cross-coupling reaction of aryl halides with alkynylsilanes. The combination of 3 mol % Pd(OAc)(2) and 6 mol % IMes.HCl in the presence of Cs2CO3 as base proves to be a highly efficient system in assisting coupling of aryl bromides with alkynylsilanes.
