AbstractAn efficient method for carbon‐carbon bond formation is described. The process employs the palladium‐catalyzed copper‐mediated cross‐coupling of diheteroaryl disulfides with arylboronic acids or alkynes to deliver CC coupling products through unreactive CS bond cleavage. The scope of the coupling reactions, including both the disulfides and arylboronic acids or alkynes, are documented.magnified image

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.

cross‐coupling reaction of 1, 2‐di(pyrimidin‐2‐yl) disulfides with heterocyclic amines including 2‐amino pyrimidines and 1,3,4‐thiadiazol‐2‐amines to deliver symmetrical C‐N coupling products in moderate to good yields is reported. This method provides an opportunity for synthesis of bioactive molecules and pharmaceutically interesting compounds containing heterocycle motifs. The reported protocol shows good functional

A method for synthesizing C2 functionalized pyrimidine derivatives by phenylalkyne and pyrimidine disulfide under environmental conditions with good group compatibility is reported. Furthermore, density functional theory (DFT) calculations confirm that it is more advantageous to generate C2-functionalized pyrimidine derivatives.
