We have successfully achieved the molybdenum hexacarbonyl [Mo(CO)6] mediated desulfurization of thiols and disulfides. In this reaction, the sulfhydryl (SH) mercapto groups of aryl, benzyl, primary and secondary alkyl thiols, and S–S single bonds of disulfides can be removed. This reaction has high functional group tolerance and is not affected by steric hindrance. The results of the reactions in acetone-d

Copper-catalyzed synthesis of benzo[d]isothiazol-3(2H)-ones and N-acyl-benzothiazetidine by intramolecular dehydrogenative cyclization is described. In this reaction, a new nitrogen–sulfur (N–S) bond is formed by N–H/S–H coupling. The present reaction has high functional group tolerance and gives products in gram scale. This method promotes double cyclization, allowing for synthesis of a drug intermediate
描述了铜通过分子内脱氢环化反应合成苯并[ d ]异噻唑-3(2 H)-酮和N-酰基-苯并噻唑烷的方法。在该反应中,通过NH / S-H偶联形成一个新的氮-硫(NS)键。本反应具有较高的官能团耐受性,并得到以克为单位的产物。该方法促进了双环化,从而允许合成药物中间体。
