Abstract

A simple, efficient and sustainable method for the general synthesis of NHC gold(I) complexes is described. The reaction of imidazolium salts, of different electronic and steric requirements, with [AuX(tht)] (tht = tetrahydrothiophene) derivatives, in the presence of NBu4(acac), in air and at room temperature leads to the NHC gold species in good yields and with very short reaction times.
