Abstract: | A variety of novel N-t-butyl-N'-aminocarbonyl-N-(substituted)benzoylhydrazines containing a -aminoalkylphosphonate groups were synthesized by the addition of N-t-butyl-N-(substituted)benzoylhydrazines to a -isocyanatoalkylphosphonates, which were synthesized by the reaction of a -aminoalkylphosphonates with triphosgene in good yields. The structures of products including by-products were confirmed by 1H NMR, 31P NMR, IR, mass spectroscopy, and elemental analysis. |
