摘要：

The major pathways for the fragmentation of dihydrosilaazaanthracenes, containing an azetidine substituent, spiro-beta-lactam ring, or spirotetrahydrofuryl residue at C-9 upon electron impact are related to the presence of these rings. The azetidine ring may be eliminated as a radical or by splitting "in half" to give [M - Me]+ ions. Splitting of the spiro-beta-lactam ring "in half" leads to the two strongest ions M+.. The loss of the tetrahydrofuryl ring leads to ions of 9-methylene- and 9-oxosilaazaanthracenes. The dimethylsilyl group loses a methyl radical at various stages of the decomposition.
