Method for preparing phosphinic acid ester/phosphorous acid ester/phosphoric acid ester from P(O)-OH compound and aryl boronic acid

The invention provides a method for high-selectivity synthesis of phosphinic acid ester/phosphorous acid ester/phosphoric acid ester derivatives containing different substituted functional groups; a metal salt is used as a catalyst, a P(O)-OH-containing compound and aryl boronic acid are used as reactants, and an alkali, an additive and an organic solvent are added into the reaction system. The method has the advantages that the catalyst is cheap and easy to obtain; the reaction conditions are mild, and the method is safe and reliable; the selectivity of the obtained target product is close to 100%, and the yield is as high as 90% or more. The method solves the deficiency that traditional synthetic phosphinic acid ester/phosphorous acid ester/phosphoric acid ester compounds have poor reaction selectivity, complex reaction steps and low yield and need to use reagents harmful to the environment, and has a good prospect in industrial application. The invention also provides the corresponding phosphinic acid ester/phosphorous acid ester/phosphoric acid ester derivatives correspondingly containing different substituted functional groups.

Process to prepare alkyl phenyl phosphates

The present invention relates to a process to prepare dialkyl monophenyl phosphate, monoalkyl diphenyl phosphate or mixtures thereof wherein dichloromonophenyl phosphate and/or monochlorodiphenyl phosphate is reacted with an aliphatic alcohol in the presence of a Lewis acid catalyst and in the absence of solvent at a temperature of 40 to 200°C and a pressure of 0 to 1 bar. The present invention further relates to mixtures of monoalkyl diphenyl phosphates and dialkyl monophenyl phosphates obtainable from the above process and the use of such mixtures as a plasticiser and/or a flame retardant.
