A regioselective rhodium-catalyzed thiolation of N-tosyl acrylamides with readily available disulfides has been developed. Through N-tosylamide-assisted activation of the alkenyl C(sp)-H bond, a series of ( Z)-alkenyl sulfides were constructed in moderate to excellent yields with good tolerance of functional groups. Turnover numbers (TONs) of up to 7100 were obtained utilizing 0.01 mol % Rh catalyst. In addition, diphenyl diselenide was also successfully applied to this reaction for the construction of ( Z)-β-alkenyl selenides under identical conditions.
发展了一种区域选择性的铑催化 N-对甲苯磺酰丙烯酰胺与易得的二硫化物的硫代反应。通过 N-对甲苯磺酰胺辅助的烯基 C(sp)-H 键的活化,一系列(Z)-烯基硫醚在中等至优异的产率下构建,对官能团具有良好的耐受性。利用 0.01 mol% Rh 催化剂,TON 值高达 7100。此外,二苯基二硒醚也可成功应用于该反应,在相同条件下构建(Z)-β-烯基硒醚。
