REACTION OF THIOLO AND SELENOLO ESTERS OF PHOSPHORUS ACIDS WITH HALOGENS. 4. HALOGENOLYSIS OF O,O-DINEOPENTYL Se-METHYL (PHENYL) PHOSPHOROSELENOATES

Abstract

Abstract It has been demonstrated that the reaction of the title phosphoroselenoates with halogens and sulphuryl chloride occurs more readily than that of sulphur analogues. The participation of diphosphorus inter-mediates, (NeoO)2P(SeR)OP(O)(ONeo)2X− has been shown. It was found, that the increased leaving ability of —SeR group strongly influences the decomposition pathways of the latter compounds, leading to the different compositions of the final reaction products from those observed previously for the same reactions of analogous thiolo esters.
