Thermochemical Data of Organic Ions Obtained from Investigations in the More or Less "Diluted" Gas Phase.
How is a proton bound to an arene, how mobile is it in such a complex, and how much energy is required to remove it-these questions have been of fundamental interest in physical organic chemistry for half a century. The experimental determination of quantitative thermochemical data of organic elementary processes in the gas phase is discussed for recent examples, such as the alpha-acidification of tertiary amines by complexation with boranes (see reaction) and the "local" C(alpha)-H acidities of alpha,alpha,alpha-trifluoromethylbenzene and higher analogues.
