Abstract
In contrast to the previously investigated 1-silalactones, ejection of a CO2 molecule from the molecular ion is not characteristic in the disintegration of 2- and 4-silalactones under electron impact. Migration of the silicon atom to the oxygen atom during fragmentation of the 2- and 4-silalactones was observed. The dependence of the paths of disintegration of the silalactones on the ring size and the number of methylene links was established. The possibility of the identification of isomeric 2-silalactones on the basis of their mass spectra was observed.
