Abstract
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 solve nt. The structures are supported by elemental analysis, H-1, (PNMR)-P-31, M ass 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 co mpounds.
