ABSTRACT:
A process for preparing cyanophosphonate derivatives involves contacting a pyrophosphate ester or a polyphosphate ester and cyanide in a reaction mixture under conditions sufficient to produce the cyanophosphonate derivative. The cyanophosphonate derivative product can subsequently be hydrogenated to produce an aminomethylphosphonate derivative.
