The mass spectra of allyloxydimethylsilanes and allyloxytrimethylsilanes were examined. Isotopic labelling and metastable peaks support the proposed fragmentation patterns. Siliconium ions dominate the spectra. Loss of neutral fragments from [M—15] + and [M—1] + ions is important. These fragmentation patterns are discussed in terms of interaction of siliconium ions with the carbon‐carbon double bond of the allyloxy ligand. Increased substitution on the allyloxy ligand apparently decreases the interaction of siliconium ions with the carboncarbon double bond.
