Ph3P-mediated decarboxylative ring-opening of maleic anhydride by thiolic compounds: formation of two carbon-sulfur bonds.

In this study, a simple and efficient method for the formation of carbon-sulfur bonds is described. In this process, ring opening of maleic anhydride by thiols or disulfides and triphenylphosphine led to the formation of sulfide products via formation of two carbon-sulfur bonds.
