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。

Molecular iodine catalysis of additions of various substituted thiophenols to indene to afford the corresponding sulfides in good yields under mild conditions is reported. The regioselectivity of addition can be fine-tuned by modifying the reaction conditions, and the addition can also be effected under solvent-free conditions.[GRAPHICS].
