High resolution mass spectrometric study of organosilicon compounds. Siloxazolidones: Cyclized amino acid-silane derivatives

High resolution mass spectra have been obtained for a series of methyl, ethyl and phenyl substituted siloxazolidones (cyclic compounds derived from the condensation of organosilane derivatives with amino acids). The effects on the mass spectra of these compounds upon substitution at the saturated ring carbon and at the silicon atom, the migratory nature of the phenyl group on nitrogen, and theextent of biphenyl radical ion formation in the skeletal rearrangement processes have been examined.
