2, 4, 6-trimethyl benzoyl phenyl phosphinic acid ethyl ester preparation method

The invention relates to a preparation method of 2,4,6-trimethyl benzoyl phenyl ethyl phosphonate, and in particular relates to a method for preparing 2,4,6-trimethyl benzoyl phenyl ethyl phosphonate through the steps of carrying out substitution condensation reaction on dichlorophenyl phosphine and ethanol to obtain an intermediate; performing condensation reaction on the intermediate and 2,4,6-trimethyl benzaldehyde under an alkaline condition, and finally performing oxidation by using an oxidant under catalysis of a catalyst. The preparation process of 2,4,6-trimethyl benzoyl phenyl ethyl phosphonate, disclosed by the invention, has the advantages as follows: the influences of an acidic medium on the intermediate can be avoided; the requirements of the condensation reaction between 2,4,6-trimethyl benzaldehyde and phenyl ethyl hypophosphite for reaction equipment can be reduced; meanwhile, the reaction yield can be ensured; the preparation process is simple in operation and is suitable for industrial production.

ORGANOPHOSPHORUS CHEMISTRY. 2. THE REDUCTION OF QUINQUEVALENT PHOSPHORUS TO THE TRIVALENT STATE

Phosphoryl and phosphonyl chlorides are reduced conveniently to the monobasic acid forms of the corresponding phosphorous and phosphonous acids by the use of sodium borohydride dispersed in dioxane.
