PHASE-TRANSFER CATALYSIS (PTC) IN ORGANOPHOSPHORUS COMPOUNDS SYNTHESIS. 1: LIQUID-LIQUID PTC SYNTHESIS OF PHOSPHORODICHLORIDOTHIOIC ACID O-ARYL ESTERS

摘要

Phase-transfer catalysis in the organophosphorus compounds synthesis reaches every day new limits. Our aim was to investigate the possibilities to apply this kind of catalysis to some organophosphorus compounds in different systems. Moreover, for the systems used, the best conditions were fond out, since this kind of reactions are influenced by many factors. In this first article the methods used in the phase-transfer synthesis, in liquid-liquid system, of the phosphorodichloridothioic acid O-aryl esters are presented. The following paper will concern the influence of different factors on the yield and purity of the obtained substances.
