摘要

Process for obtaining phosphoric, phosphonic, phosphinic and thionophosphoric, thionophosphonic, thionophosphinic acid esters, characterized in that the halides of the (thiono) phosphoric acid (phosphonic, phosphinic) ester of the general formula ** (See formula) ** where R and R 'are low alkyl or alkoxy groups, preferably with 1-4 carbon atoms, as well as aryl radicals, X means an oxygen or sulfur atom and Hal a halogen atom, are reacted with bisulfides, , 4'-dihydroxy-diphenyls of formula ** (See formula) ** where Y and Y ', represent hydrogen, halogen or low alkyl groups, the reaction being carried out in the presence of inert organic solvents and acid binding media, at a temperature from light to moderately high, applying mechanical means to activate the reaction.
