摘要: The fragmentation pathways of protonated imine resveratrol analogues in the gas-phase were investigated by electrospray ionization-tandem mass spectrometry. Benzyl cations formed that had an ortho-hydroxyl group on benzene ring A. specific elimination quinomethane neutral, CH2 = C6 H4 = O, from two isomeric ions [M1 + H](+) and [M3 + H](+) via corresponding ion-neutral complexes was observed. pathway for related meta-isomer, ion [M2 + H](+) other congeners not Accurate measurements additional experiments carried out with a chlorinated analogue trideuterated isotopolog M1 supported overall interpretation phenomena It is very helpful understanding intriguing roles effect reactions enriching knowledge chemistry benzyl cation.
