A versatile Cu-catalyzed cross-coupling reaction to various unsymmetrical disulfanes has been presented, from phthalimide-carried disulfur transfer reagents and commercially available boronic acids under mild and practical conditions. The method features the unprecedented use of phthalimide-carried disulfurating reagents (Harpp reagent) in cross-coupling chemistry and is highlighted by the broad substrate scopes, even applicable for the transfer of aryl-disulfur moieties (ArSS-). Notably, the robustness of this methodology is shown by the late-stage modification of bioactive scaffolds of coumarin, estrone, and captopril.

Novel disulfuration was established via cross coupling between nucleophilic disulfurating reagent and arylsilane introducing two sulfur atoms in one step. This methodology was applied to synthesize various unsymmetrical disulfides under mild conditions via copper-catalyzed oxidative Hiyama-type cross coupling, providing a new pathway for disulfide synthesis. In addition, pH value of system displayed a key role in alcoholysis process.
