ABSTRACT:
A process for preparing cyanophosphonate derivatives involves contacting phosphoric anhydride (P.sub.4 O.sub.10) and a cyanide, preferably in the presence of a Lewis base, in a reaction mixture under sufficient conditions to produce a cyanophosphonate derivative. The cyanophosphonate derivative can be subsequently hydrogenated to produce an aminomethylphosphonate derivative.
