✦ Synopsis

Electron impact induced fragmentations of diethoxydimethylsilane (1) and its deuterium-labelled analogues (2 and 3) were investigated by mass-analysed ion kinetic energy spectrometry. The principal fragmentation processes of compound 1 are dominated by silicenium ions which undergo consecutive losses of ethylene and aldehyde molecules. The fragmentations of 1 led to the formation of protonated silanoic acid [CH,Si(OH),I+ and protonated dimethylsilanone [(CH,),Si=OW+, and their unimolecular reactivities were clarified. The fragmentation characteristics of compound 1 are compared with those of the carbon analogue, acetone diethyl acetal(4).
