  A mechanistic study of the prominent loss of H2O from ionized 2-hydroxyaminoethanol

  摘要：

  Tandem mass spectrometry experiments on the HCl salt of 2-hydroxyaminoethanol reveal that low-energy ions HOCH2CH2NHOH center dot+ dissociate by loss of H2O with remarkable efficiency (c. 10%). Analysis of its high energy collision-induced dissociation (CID) mass spectrum leaves little doubt that the resulting m/z 59 ion is the cyclic 1,2-oxazetidine ion, whose elusive neutral counterpart has not yet been identified by experiment.A mechanistic analysis using the CBS-QB3 model chemistry indicates that the dissociation chemistry of HOCH2CH2NHOH center dot+ is entirely different from that of the structurally related ions HOCH2CH2ONH2 center dot+ and HOCH2CH2OH center dot+. It involves a 1,5-H transfer in one of its stable conformers that leads to a hydrogen-bridged radical cation of the 1,2-oxazetidine ion and a water molecule. In support of this proposal the isotopologues DOCH2CH2NDOD center dot DCl and HOCH2CD2NHOH center dot HCl, upon ionization (almost) exclusively lose D2O and H2O, respectively. (C) 2010 Elsevier B.V.
