The equilibrium acidities (pK(HA) values) in DMSO of the following hydroxylamines have been measured: (1) N-phenylhydroxylamine and its p-bromo and p-cyano derivatives, (2) N-benzyl-N-phenylhydroxylamine and its p-bromo and p-cyano derivatives, (3) O-benzyl-N-phenylhydroxylamine, (4) N-benzoylphenylhydroxylamine and its p-bromo and p-cyano derivatives, and (5) N-hydroxylpiperidine. The BDEs of the O-H and/or N-H bonds in these 11 weak acids have been estimated by combining their pK(HA) values with the oxidation potentials of their conjugate bases according to the following equation: BDE(HA) = 1.37pK(HA) + 23.1E(ox)(A-) + 73.3 kcal/mol.
