Abstract
Recently we have evaluated 1 the bond dissociation enthalpies (BDE) of the O–H bonds of a variety of hydroxylamine derivatives, showing how the BDE values strongly increase from alkyl- or arylhydroxylamine (≈70 kcal mol −1 ) to mono- and di-acylhydroxylamines (88.1 kcal mol −1 for N-hydroxyphthalimide, NHPI). Moreover, we have determined 1 the absolute rate constant for hydrogen abstraction from a series of C–H bonds by phthalimido-N-oxyl ...
