A rapid and facile method provides a general route to sulfonyl bromides/chlorides by the oxidation of thiols using NXS – ROH (X = Br,Cl, R = iPr) as an oxyhalogenation reagent. Control experiments suggest that the alcohol component is the source of oxygen. The proposed method enable the access to structurally diverse sulfonyl bromides and chlorides including challenging examples, inaccessible by other synthetic methods.

使用NBS / NCS – i PrOH通过硫醇氧基卤化合成磺酰卤
一种快速而简便的方法,是使用NXS – ROH(X = Br,Cl,R = i Pr)作为氧卤代试剂氧化硫醇,从而提供了磺酰溴/氯化物的一般途径 。对照实验表明,酒精成分是氧气的来源。所提出的方法使得能够获得结构上不同的磺酰溴和氯化物,包括具有挑战性的实例,这是其他合成方法所无法达到的。
