Herein, we report a borane-promoted reductive deoxygenation coupling reaction to synthesize sulfides. This reaction features excellent functional group compatibility, high efficiency, broad substrate scope, and application in late-stage functionalization of biomolecules. Preliminary mechanistic studies suggest diaryl sulfides are the intermediates of this reaction. Moreover, the real active aryl sulfide
在此,我们报告了一种硼烷促进的还原脱氧偶联反应来合成硫化物。该反应具有官能团相容性好、效率高、底物适用范围广等特点,可应用于生物分子的后期官能化。初步机理研究表明二芳基硫化物是该反应的中间体。此外,真正的活性芳基硫阴离子可以在B 2 pin 2的帮助下原位生成,并通过协同的S N 2 途径与烷基甲苯磺酸盐反应。

A method for producing a polydiene, the method comprising the steps of (i) forming an active catalyst by combining a lanthanide-containing compound, an alkylating agent, and a halogen source in the substantial absence of an organosulfide; and (ii) polymerizing conjugated diene monomer in the presence of the active catalyst and an organosulfide.
