使用磺酰肼作为亚硫基源，已经开发了碳-硼键的前所未有的亚硫基化反应。一系列磺酰肼在空气中与硼酸进行四（乙腈）四氟硼酸铜（I）[Cu（CH 3CN）4 BF 4]/2，2 ′-联吡啶催化的亚磺酰化反应，以中等至良好的产率得到结构不同的硫醚。初步的机理研究表明，磺酰肼分解成硫代磺酸盐和二硫化物，然后与硼酸形成碳硫键。
An unprecedented sulfenylation reaction of carbon‐boron bonds has been developed using sulfonyl hydrazides as sulfenyl sources. A range of sulfonyl hydrazides underwent tetrakis(acetonitrile)copper(I) tetrafluoroborate [Cu(CH3CN)4BF4]/2,2′‐bipyridine‐catalyzed sulfenylation with boronic acids under air to give structurally diverse thioethers in moderate to good yields. Preliminary mechanistic studies show that sulfonyl hydrazides are subjected to decomposition into thiosulfonates and disulfides followed by formation of carbon‐sulfur bonds with boronic acids.
