A simple and efficient method for the formation of C?S bond via direct functionalization of C(sp3)?H bond adjacent to heteroatoms was described under metal-free conditions. In this work, stable and easily accessible sodium sulfinates were used as the thiolating agents to afford various aryl thioethers in moderate to excellent yields. Mechanistic explorations show that a radical pathyway is possibly involved during the transformations. (Figure presented.).

A simple and efficient method for the preparation of α-arylthioethers through a visible-light-induced direct thiolation at α-C(sp3)-H of ethers with diaryl disulfides was developed using acridine red as a novel photocatalyst. The reactions occurred at ambient conditions and generated the corresponding products in good to excellent yields, ignoring steric effect of disulfides.

, p. 5028 - 5035 (2014/06/23)
In sharp contrast to many examples of transition-metal-catalyzed hydrothiolation of alkynes, the corresponding catalytic addition of thiols to alkenes has remained undeveloped. However, a novel Pd-catalyzed addition of thiols to alkenes bearing a heteroatom, such as oxygen and nitrogen, is found to proceed under mild conditions to give the corresponding Markovnikov adducts, regioselectively, in good yields.

A new tert-butyl hydroperoxide (TBHP)-mediated oxidative cross-coupling of disulfides with ethers is presented for the synthesis of etherified sulfides. This method is achieved by a C(sp3)-H thiolation strategy under metal-free conditions and provides a simple route to constructing the C-S bonds. Copyright
