8. This is consistent with the Δδ of 1.80 ppm obtained for benzylic protons of 6 in which all of the aromatic rings are thought to be parallel; Yamada, A.; Murase, T.; Kikukawa, T.; Arimura, T.; Shinkai, S. J. Chem. Soc., Perkin Trans. 2 1991, 793-797.
9. 6-DMSO did not appear to produce a pronounced effect, as the spectra obtained in these solvents at 330 K are virtually identical.
