Dehydrogenation reaction is a thermodynamically favorable process from a dihydrogenbond (E-H. . . . H-X) due to large free energy for the formation of molecular hydrogen. The dihydrogen bond is often thought to be an intermediate or a transition state for such a reaction. Mass spectrometric evidence for the dehydrogenation reaction in the gas phase, following resonant multiphoton ionization of dihydrogen bonded complex between phenol and borane-trimethylamine in the supersonic free jet will be presented.
