Abstract

Procedure for the preparation of benzyl phosphonates of formula I **(See formula)** in which R1 and R2 signify a straight chain or branched alkyl group, a cycloalkyl group or an aralkyl group, while R3 and R4, independently of one another, mean a straight or branched chain alkyl group, a cycloalkyl group, an alkylthioalkyl group, an alkyloxalkyl group, a haloalkyl group, an alkenyl group, the phenyl group or an alkylphenyl group; or together the groups **(See formula)** characterized by reacting 1 mol of a compound of formula II **(See formula)** in which R1 and R2 have the same meaning that has been attributed to them before, while R5 and R6 independently of one another signify a straight chain or branched alkyl group; or, together and including the nitrogen atom, they form a saturated heterocyclic ring, with 1 mol of a compound of formula III **(See formula)** in which R3 and R4 have the same meaning that has been attributed to them before, in the presence of a base.
