The dissociation chemistry of low-energy N-formylethanolamine ions: Hydrogen-bridged radical cations as key intermediates
Abstract
Tandem mass spectrometry experiments show that N-formylethanolamine molecular ions HOCH2CH2NHC(H)O+ (FE1) lose C2H3O, CH2O and H2O to yield m/z 46 ions HC(OH)NH2+, m/z 59 ions CH2N(H)CHOH+, and m/z 71 N-vinylformamide ions CH2C(H)N(H)CHO+.A detailed mechanistic study using the CBS-QB3 model chemistry reveals that the readily generated 1,5-H shift isomer HOCHCH2N(H)C(H)OH+ (FE2) and hydrogen-bridged radical cations (HBRCs) act as key …
