Peracid oxidation of ,,′ ,′-tetrasubstituted phosphorodiamidothiolates in chloroform yields, among other products, the corresponding phosphinyloxysulfonates the alkylsulfonic acids by both SN1 and SN2 type mechanisms with their relative contribution determined by the concentration of the sulfonic acid. The first products (t 10–50 min) in the oxidation sequence are tentatively assigned by 1H, 13C and
在其他产品中,,,,,- ,- ,-,-四取代的硫代二氨基硫代磷酸酯的过酸氧化产生了相应的次膦酰氧基磺酸,通过S N 1和S N 2型机理使烷基磺酸产生,它们的相对贡献取决于磺酸的浓度。氧化顺序中的第一个产物(t 10-50分钟)由1 H,13 C和31 P NMR暂定为硫代磷酸亚砜和砜。
