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

Hydrophosphonylation reactions have emerged as efficient processes for the functionalization of alkenes or alkynes. Synthesis of alkylphosphonates was achieved by an original double radical transfer mediated by titanocene and propylene oxide. By the same way, nitriles which are considered as inert functions in radical process lead to aminobisphosphonates. (C) 2011 Elsevier Ltd. All rights reserved.
