Pulse technique pyrolysis of some arylsilanes and their thermal reaction with aliphatic, aromatic alcohols over Ni-Y-Zeolite

P-tolyltrimethylsilane and phenyltrimethylsilane were subjected in the gas phase to pyrolysis and thermolysis reactions with alcohols and phenols at different temperatures over Ni-Y-zeolite using a pulse catalytic technique. The obtained alkoxy- and phenoxy- trimethylsilanes with other side products were identified by gas liquid chromatographic analysis. The yield in each case varied with the reaction temperature. The highest yield was obtained at 250C. The different pathways of these thermolytic reactions were discussed and the results were assigned
