Abstract

In view of the importance of trimethylsilyl ethers in gas chromatography, the basic fragmentation modes incurred upon electron bombardment of polymethylene glycol bistrimethylsilyl ethers (111, n= 2-8) were elucidated; in all cases (n= 2-8), there is encountered a characteristic rearrangement ion (g) of mass 147 involving expulsion of the central portion of the molecule. Electron bombardment of the corresponding methoxy-(XI, ...
