An efficient method for the synthesis of thiolated cyclic N‐sulfonyl ketimines has been developed. The reaction proceeds via rhodium catalyzed C−H functionalization using disulfides in the presence of silver carbonate, silver triflate and copper acetate in toluene. The methodology showed broad substrate scope as a wide range of N‐sulfonyl ketimines participated in the reaction giving the thiolated products in up to 95%.

铑催化的环N-磺酰基酮亚胺的直接邻位C H硫代反应

已开发出一种有效的合成硫醇化环状N-磺酰基酮亚胺的方法。反应在甲苯中存在碳酸银，三氟甲磺酸银和乙酸铜的情况下，使用二硫化物通过铑催化的CH官能化进行。该方法显示了广泛的底物范围，因为广泛的N-磺酰基酮亚胺参与了反应，使硫醇化产物的产率高达95％。
