PECULIARITIES OF INTERACTION OF H-PHASE(, ME(3)C(+), AND ME(3)SI(+) IONS WITH MULTIFUNCTIONAL MOLECULES IN THE GAS)

Peculiarities of interaction of H+, Me(3)C(+), and Me(3)Si(+) ions wit h functional groups of molecules in the gas phase have been studied. P roton tends to form chelates with virtually all of the functional grou ps studied, whereas Me(3)Si(+) ions exhibit no capacity for chelation. Using isomeric xylenes as examples it was shown that Me(3)Si(+) ions (unlike Me(3)C(+) ions) experience virtually no steric hindrance when they react with nucleophilic centers. Effects of functional groups pre sent in molecules of nitriles on the generation of [M+Me(3)C](+) adduc ts in the gas phase and the Ritter reaction in solution were estimated .
