of unsymmetrical diaryl disulfides under mild conditions in excellent yields. The described method is based on the straightforward preparation of 5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorinane-2-sulfenyl bromide from readily available 5,5-dimethyl-2-sulfanyl-2-thioxo-1,3,2-dioxaphosphorinane or bis(5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorinan-2-yl) disulfide. The unsymmetrical diaryl disulfides can
我们开发了一种在温和条件下以优异收率合成不对称二芳基二硫化物的简便方法。所述方法基于从容易获得的 5,5-dimethyl-2-sulfanyl-2-thioxo-1 直接制备 5,5-dimethyl-2-thioxo-1,3,2-dioxaphosphorinane-2-sulfenyl bromide ,3,2-二氧杂膦烷或双(5,5-二甲基-2-硫代-1,3,2-二氧杂膦-2-基)二硫化物。不对称二芳基二硫化物可由带有吸电子或给电子基团的芳族硫醇衍生物获得。
