Unimolecular Reactions of Diethyl Malonate Cation in Gas-phase

open access: bronzeJournal of the Mass Spectrometry Society of Japan, 2004
Unimolecular reactions of diethyl malonate cation (CH3CH2OC(=O)CH2C(=O)OCH2CH3+· ; 1+·, Mw : 160) induced by electron ionization, have been investigated by use of mass-analyzed ion kinetic energy (MIKE) spectrometry and D-labeling in conjunction with thermochemistry.
