C-O and C-S coupling reaction of 1,2-di(pyrimidin-2-yl) disulfides with phenols/thiophenols promoted by copper(I) chloride

Abstract

An efficient protocol for C-O and C-S bonds formation by the cross-coupling reaction of 1,2-di(pyrimidin-2-yl) disulfides with phenols/thiophenols promoted by copper(I) chloride was established. It was discovered that variously substituted di(hetero)aryl disulfides and phenols were well tolerated. This strategy is the conversion of disulfides into hetero-aryl ethers and thioethers by a copper-promoted chemoselective C-S bond cleavage of disulfides.
