    • The surprisingly poor performance of HMPA as an additive may have been due to impurities in the HMPA. Given the health concerns associated with the use of HMPA, we chose to focus on the use of DMPU as an additive.

    • 3) carbon atoms. For overlapping signals, the number of carbon atoms is given in parentheses. Capillary GC analysis was performed on a Hewlett Packard Model 6890 instrument with a 30 m PhMe-Silicon column, a flame ionization detector, and a Hewlett Packard computer-interfaced integrator. Combustion analysis were performed by M-H-W Laboratories, Phoenix, AZ. Mass spectra were determined on an AE2-MS 30, a PG 7070E-HF, a CG Analytical 7070E, or a Fisions autospec spectrometer.
