A convenient method for the synthesis of aryl methyl sulfides via Cu(I)-mediated methylthiolation of haloarenes with DMSO

An efficient process for the Cu(I)-mediated methylthiolation of haloarenes using simple and readily available DMSO as a convenient and environment friendly source of SMe moiety has been developed. In the presence of CuI and DABCO, a variety of aryl/heteroaryl halides reacted with DMSO to afford corresponding aryl methyl sulfides in good to excellent yields. (C) 2015 Elsevier Ltd.
