Synthetic approaches are developed to benzimidoylphosphoryl derivatives containing electronically and sterically diverse alkyl substituents on the nitrogen atom, as well as their prototropic isomers. Regularities in prototropic transitions in the phosphorylated C=N-C triad were revealed and applied in the synthesis of α-aminophosphonic acid derivatives.
