Popis: A number of 2-ethoxycarbonyl phenylseleno aminomethylene phosphonates have been synthesized by the Mannich-type reaction of 1,2-benzisoselenazol-3(2H)-one, formaldehyde and dialkylphosphite with anhydrous ethanol as the solvent. The structures are supported by elemental analysis, 1H, 31PNMR, Mass and IR spectra. It was found that ethanol participates in the reaction and leads to the opening of 1,2-benzisoselenazol-3(2H)-one to form title compounds.
