Reaction of Free Methyl Cation with (Isobutylamino)trimethylsilane in the Gas Phase. A Radiochemical and Quantum-Chemical Study

The reaction of free methyl cation with (isobutylamino)trimethylsilane was studied by the radiochemical method. Like with organic amines and silazane, the reaction occurs by two channels: condensation and proton transfer. Proton transfer remains to be the major reaction channel, while its contribution is less that with amines and silazane. The radiochemical and quantum-chemical methods were used to show that the condensation and proton-transfer complexes decompose primarily via Si-N bond cleavage.
