, p. 228 - 232 (2016)
Amino derivatives of methylenebisphosphonic acids were synthesized by phosphorylation of formamide, nitriles or hydrochlorides of alkyl imidates with H3PO3—PCl3—(Me3Si)2NH.

The convenient methods for the synthesis of new trimethylsilyl esters of aminomethylenediphosphonic acids are elaborated. The new substituted N-formylaminomethylenediphosphonates are obtained via the interaction of trimethylsilyl esters of methylenediphosphonic acids with a mixture of triethyl orthoformate and ethanol. Also boron trifluoride-diethyl etherate as an effective catalyst is used for the interaction of hydrochlorides of ethoxymethylene imines with diethyl trimethylsilyl phosphite. The corresponding aminomethylenediphosphonic acids are presented.

The interaction of trimethylsilyl esters of trivalent organophosphorus acids containing PH and POSiMe3 groups with hydrochlorides of ethoxymethylene imines is a convenient method for the synthesis of new trimethylsilyl esters of N-unsubstituted aminomethylenebisorganophosphorus acids with three and four coordinated phosphorus. Also trimethylsilyl trifluoromethanesulfonate as effective catalyst is used for the similar interaction of hydrochlorides of ethoxymethylene imines with tris(trimethylsilyl)phosphite. The corresponding bisorganophosphorus acids and their derivatives are presented.
Synthesis of new types of aminomethylenediphosphorus-containing acids and their derivatives
Prishchenko,Livantsov,Novikova,Livantsova,Ershov,Petrosyan
, p. 370 - 379 (2015/04/14)
Convenient methods for synthesis of various aminomethylenediphosphorus-containing acids and their derivatives starting from available trimethylsilyl esters of hypophosphorous and phosphorous acids, ethoxymethyleneimine hydrochlorides, and N-substituted formamides have been proposed. Selected properties of the obtained compounds have been examined.
