t-Butyldimethylsilyl Derivatives of Some Alkylphosphonic and Alkyl Methylphosphonic Acids. Part 1. Gas Chromatographic/Mass Spectrometric Studies

摘要

Electron impact mass spectra have been generated for t-butyldimethylsilyl derivatives of several alkyl methylphosphonic, alkylphosphonic and halogen-substituted alkylphosphonic acids. In all cases, fragmentation is limited to a few abundant ions indicating that improved quantitation of this class of compounds, essential for verification of chemical arms agreements, will be possible by gas chromatographic/mass spectrometric means using these derivatives. Some fragmentation mechanisms are suggested to account for the major ions of the spectra.
