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

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.

A general protocol for the chemoselectivity-controlled C-C and C-S coupling reactions of di(hetero)aryl disulfides with Grignard reagents catalyzed by ferrocene and palladium acetate has been developed. Ferrocene favored the formation of C-S coupled products at low temperature, whereas C-C bond couplings were favored when palladium acetate was used. All the reactions proceeded with excellent chemoselectivity and in good yields under mild conditions, and a library of molecules with pyridine and pyrimidine scaffolds was produced.

A wide range of Biginelli 4-aryl-3,4-dihydropyrimidin-2(1H)-thiones undergo ligand-free C-S cross-coupling with diaryliodonium triflates in the presence of CuO nanoparticles with the concomitant oxidative aromatization to form highly substituted 2-(thioar
