Base-catalysed decomposition of nitramide: kinetic isotope effects
Abstract
Kinetic hydrogen isotope effects on the decomposition of nitramide catalysed by a series of phosphonate anions and the 2,4,6-trichlorophenoxide ion were found to be small (kH/kDca. 2–3) with no sign of a maximum value of pKa(catalyst conjugate acid)ca. 6, in disagreement with a previously reported claim but consistent with the expected pKa of the reactive form of the substrate.
