Abstract

Phosphonium-phosphate derivs. of formula (I) are prepd., opt. in a continuous process, as follows: R = 1-4C and X = halogenide. In case of more than one halogenide they may be same or dissimilar. Benzoyl-phosphonate (II) is prepd. by adding a tri:alkyl-phosphate (IV) to benzoyl-halogenide (V) in 1:1 molar proportion. Benzoyl-phosphonate (II) pred. above and di:alkyl-phosphonate (III) yields (I). This reaction proceeds in the presence of a base pref. di:n-butyl-amine and in an inert solvent pref. toluene. The reaction is carried out directly or following the removal by distn. of alkyl-halogenide.
