在有氧条件下，以玫瑰红为光催化剂，研究了硫醇和芳肼的无金属可见光催化氧化偶联反应。在室温下以较好的产率合成了一个具有宽官能度的不对称二芳基硫醚化合物库。本方法也适用于苯并[d]噻唑-2-硫醇、苯并[d]恶唑-2-硫醇、1H-苯并[d]咪唑-2-硫醇和1H-咪唑-2-硫醇。
A metal-free visible-light-promoted oxidative coupling between thiols and arylhydrazines has been developed to afford diaryl sulfides using a catalytic amount of rose bengal as photocatalyst under aerobic conditions. A library of unsymmetrical diaryl sulfides with broad functionalities was synthesized in good yields at room temperature. The present methodology is also applicable to benzo[d]thiazole-2-thiols, benzo[d]oxazole-2-thiol, 1H-benzo[d]imidazole-2-thiols, and 1H-imidazole-2-thiol.
