Chemical ionization mass spectra of halogenoalkanes (RX) obtained using tetramethylsilane as reagent gas show two major peaks corresponding to the cluster ion RX+SiMe3 and alkyl ion R+. Iodides exhibit the highest affinity toward the trimethylsilyl ion and produce the most stable silylated molecular
## Abstract The chemical ionization mass spectra of cyclic glycols and monosaccharides using formaldehyde dimethyl acetal as reagent gas have been studied. In the gas phase, the stereospecific reaction of methylene acetal formation was observed. From the relative abundances of the characteristic io
