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

A few substituted aryldithiaphenols have been synthesized and their acid dissociations, NMR chemical shifts and UV spectra have been determined. The relatively stronger acidic nature of p-aryldithiaphenols over that of the meta-isomers is interpreted as being caused by the 3d-orbital resonance effect of the aryldithia group.
已经合成了一些取代的芳基二硫苯酚,并测定了它们的酸解离、核磁共振化学位移和紫外光谱。对芳基二硫苯酚相对于间位异构体的酸性相对较强被解释为是由芳基二硫基的 3d 轨道共振效应引起的。
