Kinetics and mechanism for the formation of o‐carboxy(N‐methyl)‐benzohydroxamic acid in the cleavage of ethyl N‐[o‐(N‐methyl‐N‐hydroxycarbamoyl)‐benzoyl]carbamate in N‐methylhydroxylamine, acetate, and phosphate buffers

Abstract

The rate of cleavage of ethyl N- [o -(N-methyl-N-hydroxycarbamoyl)benzoyl]-carbamate (ENMBC) in the buffer solutions containing N-methylhydroxylamine, acetate + Nmethylhydroxylamine, and phosphate + N-methylhydroxylamine followed an irreversible consecutive reaction path: ENMBC

Effects of mixed H2O‐CH3CN solvents on the rate of hydrazinolysis of N‐phenylphthalimide: Spectral and kinetic evidence for the occurrence of N‐aminophthalimide on the reaction path

“…But, unfortunately, data points are not sufficient to analyze the occurrence of these catalyses quantitatively. Recently, specific base, GB, GA, and GB‐HO − catalyses have been detected kinetically in cyclization of ethyl N ‐[ o ‐( N ‐methyl‐ N ‐hydroxycarbamoyl)benzoyl]carbamate to benzo‐3‐methyl‐2,3‐oxazine‐1,4‐dione within the pH range 5.45–7.28 14.…”
