Linking Ion and Neutral Chemistry in C-H Boni Electrophilic Activation: Generation ani Detection of HO2: Reactive Radicals in the Gas Phase

摘要

The activation of inert C-H bonds by charged electrophiles is the subject of extensive investigation mainly motivated by one of the most widely debated questions, that is, the conversion of alkanes into more valuable compounds. Studies of ion-molecule reactions in the idealized gaseous state have provided insightful information on this elementary step, thus lending models and concepts which span from the molecular level to the borders of the nanoscale size. These studies have shown the enhanced ability of oxygen-centered radical cations to activate C-H bonds; the inventory of XO~(·+) reactants now available includes metal oxides and oligomeric cluster ions, mixed metalonmeta! cluster ions, and also effective metal-free oxide ions.
