described of the reaction of trimethylbromosilane and trimethyliodosilane with various esters of phosphorothioic and phosphoroselenoicacids of general structures (RO)2(RY)P=O (I) and (RO)3P=Y (II) (Y = S or Se, R = alkyl). The reaction results in replacement of the R groups by trimethylsilyl groups. NoS-trimethylsilyl andSe-trimethylsilyl substituted esters were found among the products. Thus the displacement
描述了三甲基溴硅烷和三甲基碘硅烷与通式(RO)2(RY)P = O(I)和(RO)3 P = Y(II)(Y = S或Se,R =烷基)。该反应导致R基团被三甲基甲硅烷基取代。没有小号三甲基甲硅烷和硒三甲基甲硅烷取代的酯的产品中被发现。因此,II中的O -R基团的置换以及I中的S-有机基或Se-有机基的置换均导致相应的O-含有硫代磷酰基或硒代磷酰基的-三甲基甲硅烷基异构体。观察到以下酯基反应性顺序:图选项

A new thiono-thiolo allylicrearrangement of phosphoro- and phosphono-thionates with Pd(PPh3)4 catalyst is described, where a variety of thionates are converted to the corresponding thiolates in excellent yields.
