| 520 | |b The research project aim is to study the hydrolysis of 8- diethylphosphate-1-naphthalenoltriester, 1 with hydroxylamine in water. Compound 1 was successfully synthesized and its rate of reaction with hydroxylamine was monitored at 343 nm. Pseudo first order rate of P-O cleavage of 1 was measured to be 7.39× 10-3 M-1s-1 at 60 °C, which is 178 fold and 7 fold slower than diethyl 8-dimethylamino-1-naphthyl phosphatetriester, 3 at 60 °C 1.32 M-1s-1 and diethyl 8-amino-1-naphthyl phosphatetriester, 2 at 90 °C 5.5 × 10-2 M-1s-1 respectively. The rate of P-O cleavage of 1 with hydroxylamine was found to be faster than that of 4- nitrophenyl-1-cyclopropylphosphatetriester4 and 4-chlorophenyl-1- cyclopropylphosphate triester5, where the reaction was too slow to detect at 60 °C. | ||
