The electron impact and methane chemical ionization mass spectrometry of fifteen trisilanes and trisiiloxanes containing various substituents was studied with the aid of exact mass measurements and metastable ion analyses. Migration reactions of the two kinds of compounds are discussed.
The mass spectra of several 4,5-disubstituted-2-oxazolidones and several related N-methyl derivatives have been determined. Fragmentation has been found to be a function of three factors: (1) the size of the alkyl function at C-5, (2) the location of the aryl substituent, and (3) replacement of N-H
The recent communication of Karpenko and co-workers3 prompts us to disclose our related results 4 on a much wider variety of compounds. We have found that under standard mass spectrometric conditions', the molecular ions derived from a variety of 2- substituted adamantanes (1) undergo primary loss o
