An operationally simple synthetic method for (±)-α-aryl/ methylsulfonamidomethylphosphonates and new (±)-γ-aryl/methyl sulfonamidomethylvinylphosphonates has been developed through straightforward reactions of (±)-α-hydroxyphosphonates with sulfonamides in the presence of triflic acid (TfOH) at room temperature in a vessel open to air. For γ-dimethylallylhydroxyphosphonate, the (E)-1,3-butadienylphosphonate was formed quantitatively using TfOH while FeCl3 afforded the expected product in moderate yield unpredictably. The favourable sulfonoamidation of benzyl alcohol is also observed when TfOH was used for α- hydroxyphosphonates having a benzyloxy group. The Royal Society of Chemistry 2013.

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. 2004 MAIK "Nauka/Interperiodica".
Removal of Toluene-p-sulphonyl Groups from Sulphonamides. Part 5. Reactions of Phenylglyoxal Imines and some Tosylimines

Phenylglyoxal anil monomers have been shown to react with several nucleophilic reagents and the structures of the products have been elucidated.Various N-tosylarylimines also react with nucleophiles to give useful products.Phenacylimidates underwent cycloadditions with diphenylketen; such reactions gave complex results with phenacylimines, but the latter reacted with conjugated dienes in the presence of BF3 to give cycloaddition products in good yield.
