| Abstract: | Linear chloral oligomers initiated with lithium bornyl oxide and acetate endcapped were analyzed by potassium ionization of desorbed species (K+ IDS) mass spectrometry. Using this technique we observed ions resulting from the unimer]K+ with a mass of 381 daltons, to the hexamer]K+ with a mass of 1 119 daltons. Furthermore, analysis of the isotope pattern supported our structural assignment. The individual lower oligomers were also investigated by GC and NMR spectroscopy.Previous paper in this series: Haloaldehyde Polymers XL VIII. W. J. Simonsick Jr., K. Hatada, Fu Xi, and O. Vogl 27] |
