An 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 C-C coupling products through unreactive C-S bond cleavage. The scope of the coupling reactions, including both the disulfides and arylboronic acids or alkynes, are documented.

A well-defined heterogeneous palladium catalyst, natural wool supported Pd(OAc)2-complex was found to be an effective catalyst for the C-S bonds cleavage and C-C bonds formation from 1,2-di(pyrimidin-2-yl)disulfane derivatives with arylboronic acids or terminal alkynes, giving the desired coupling products in moderate to excellent yields. The novel catalyst, which is stable and easy handling in experiment, was characterized by XPS, IR, SEM and ICP analysis. Subsequent analysis of the used catalyst after reaction revealed its negligible metal leaching and at least 10 rounds of recycled catalyzing capacity and wide range of substrate tolerance.
