Gas-phase ion chemistry of silyl cations obtained from hexamethyldisilazane

Gas-phase transformation of phosphatidylcholine cations to structurally informative anions via ion/ion chemistry.

Gas-phase transformation of synthetic phosphatidylcholine (PC) monocations to structurally informative anions is demonstrated via ion/ion reactions with doubly deprotonated 1,4-phenylenedipropionic acid (PDPA). Two synthetic PC isomers, 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (PC(16:0/18:1)) and 1-oleoyl-2-palmitoyl-sn-glycero-3-phosphocholine (PC(18:1/16:0)), were subjected to this io...

Selected examples of gas-phase ion chemistry studies.

Gas-phase ion chemistry is an area in mass spectrometry that has received much research interest since the mid fifties of the last century. Although the focus of mass spectrometric research has shifted the last twenty years largely to life science studies, including proteomics, genomics and metabolomics, there are still several groups in the world active in gas-phase ion chemistry of both posit...

Mass spectrometry of alkylbenzenes and related compounds. Part I. Gas-phase ion chemistry of alkylbenzene radical cations

From the vantage point of an organic chemist, many previously obscure fragmentation and isomerization processes of gaseous organic ions have become chemically reasonable reaction pathways. The term scrambling, used formerly as a synonym for mechanistic dilemmas concerning crazy atoms, has almost vanished from mass spectrometry literature in recent years, mostly because of the recognition of wel...

Gas-phase ion chemistry in the 21st century

Biography: Fulvio Cacace was born in Rome in 193 1 and received his undergraduate education at the University of Rome, as a student of Prof. G . Giacomello. Then followed postdoctoral experience at Uppsala, Brookhaven National Laboratory, and Kernforschungauslage Julich and teaching appointments at the Universities of Camerino and Viterbo. Since 1971 he has been Professor of General Chemistry a...
