PROCESS FOR PRODUCING ORGANOPHOSPHORUS COMPOUNDS

摘要

A process for producing organophosphorus compounds by hydrolyzing the organophosphorus compound of the structural formula (1) by heating in the presence of both an excessive amount of water and an organic solvent which is insoluble in water and inert in the reaction system to thereby give the biphenyl phosphorus compound of the structural formula (2), and then subjecting the compound (2) to cyclodehydration by heating to thereby give the organo-phosphorus compound of the structural formula (3). By this process, the target compound of a high purity and excellent qualities can be produced while dispensing with special chemicals and devices made of special materials.
