摘要

A process for obtaining esters of mono- or dithiophosphoric acids of the general formula ** (See formula) ** characterized by being reacted with each other salts of the corresponding O, O-dialkyl-monothiophosphoric acids or of the O, O-dialkyl-dithiophosphoric acids of the general formula ** (See formula) ** with benzoxazoles substituted in the benzolic ring, of the general formula ** (See formula) ** preferably in an organic solvent, inert in relation to the reaction participants, and at temperatures of between 20 and 100º C, representing X oxygen or sulfur, B an alkali metal, alkaline earth metal or ammonium cation or a cation of an organic base, R and R 'lower alkyl radicals, and a halogen atom or a reactive acid radical, R "equal or different substituents, such as halogens, hydrocarbon radicals with 1-4 carbon atoms, phenyl, trifluoromethyl, NO2, carbalkoxy, alkylsulfenyl radicals , alkylsulfonyl or acyl, and two substituents can jointly form a ring, while n is an integer of 1-4.
