11. A small weight loss (ca. 2%) was observed for 1 between 100 and 300 °C. Although no significant amount of water was observed by TG-MS analysis, small amounts of water would be hard to detect as a consequence of the experimental design. Quantitative conversion of the carboxylic acids in 1 to anhydrides would produce a weight loss of 1.5%.
12. Hydrocarbons were monitored at m/e 91 and 105. The major volatile products identified by GC-MS analysis in the open tube pyrolysis of 1 and 2 were m-xylene, dimer, trimer, and tetramer (which contain m/e 91 and 105 in their mass spectral fragmentation patterns).
13. -1 was obscured by a byproduct from the reaction.
