Novel phosphonate compounds are disclosed embodying an aminophosphonate moiety and a selected reaction partner. These compounds offer beneficial alternatives, and additional possibilities, to extant phosphonates and are capable of delivering desirable benefits from an application standpoint and from a compatibility standpoint broadly.

phonic acids) has been prepared by the interaction of the corresponding chloroalkylamines or chlorobenzylamines with two equivalents each of formaldehyde and phosphorous acid in the presence of hydrochloric acid. Attempts to prepare bromoalkyl analogues gave only the chloro derivatives, resulting from halogen exchange. Compounds were characterized by carbon-13 NMR spectroscopy and fastatom bombardment

A process for the manufacture of alkylamino alkylene phosphonic acids is disclosed. In detail, a specific phosphonate is reacted with an agent selected to yield an alkylamino moiety substituted by a radical selected from OH, OR', NH2, NHR', N(R')2, NH, N, S, S-S and SH in aqueous alkaline medium having a pH of 8 or higher at a temperature of 0°C or higher.
