Abstract
A process for preparing cyanophosphonate derivatives involves contacting a phosphate ester and cyanide in a reaction mixture under conditions sufficient to produce a cyanophosphonate derivative. That cyanophosphonate derivative product can subsequently be hydrogenated to produce an aminomethylphosphonate derivative.
