| Abstract: | The hydrothiolations of alkynes/alkenes with thiols is an atom-economic and thus attractive method for the constructions of C?S bonds.Here Ir2S3/ZnIn2S4nanocomposites with varied Ir2S3loadings were obtained by one-pot solvothermal method from ZnCl2,InCl3and thioacetamide with IrCl3.The loading of Ir2S3on the surface of ZnIn2S4promoted the hydrothiolations of alkenes and alkynes,with an optimum performance observed over 0.5 mol%Ir2S3/ZnIn2S4nanocomposite.Based on the studies on the performance of several other cocatalysts(MoS2,NiS and Pd)loaded ZnIn2S4and the EIS analyses,it was proposed that the superior performance over Ir2S3/ZnIn2S4nanocomposite can be ascribed to an improved efficiency on the photogeneration of the thiyl radicals by loading Ir2S3as well as its inactivity for photocatalytic hydrogen evolution,a side reaction in the light initiated hydrothiolation reaction over ZnIn2S4.This study not only demonstrates an efficient and green strategy to synthesize thiolated products under visible light based on semiconductor photocatalysis,but also provides some guidances for the design and development of photocatalytic systems for light induced organic syntheses. |
