| Abstract: | The mass spectra of trimethylalkoxy silanes (CH3)3Si? O? (CH2)n? CH3 (n = 0-8) and (CH3)3Si? O? (CH2)n? CH(CH3)2 (n = 0-3) have been investigated and most of the fragmentations, induced by electron-impact, have been identified by metastable ions. The fragmentation mechanisms of trimethylpentoxysilane, established by Diekman, Thomson and Djerassi, are also observed in the mass spectra of these trimethylalkoxy silanes. Characteristic features of these reactions in the mass spectra of compounds with smaller and longer alkoxy groups, together with some additional fragmentations, are discussed. |
