The copper(I)-promoted cross-coupling of 1,2-di(pyrimidin-2-yl) disulfides with aromatic amines and aliphatic amines to deliver C–N coupling products in moderate to good yields is reported in this paper. Central to this strategy is the conversion of disulfides into aryl- and alkyl amines by a copper-promoted chemoselective C–S bond cleavage.

A trifluoromethylation of diheteroaryldisulfides with CF3SO2Na to afford the trifluoromethyl thioethers derivatives. The conversion has good functional group compatibility, without external photocatalyst, generating the corresponding products in moderate to good yields under mild conditions, and the disulfide is fully utilized while constructing two S‐CF3 bonds.

A general protocol for the chemoselectivity‐controlled CC and CS coupling reactions of di(hetero)aryldisulfides with Grignardreagents catalyzed by ferrocene and palladium acetate has been developed. Ferrocene favored the formation of CS coupled products at low temperature, whereas CCbond couplings were favored when palladium acetate was used. All the reactions proceeded with excellent chemoselectivity

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 chemoselectiveC-S bond cleavage
