The 13C NMR spectra of some 1and 2-substituted perimidines and perimidinium salts are discussed and assigned. Although the spectra of most of the 2-substituted perimidines are comparatively simple, several examples display I3C and 'H spectral characteristics indicative of inhibition of prototropic t
H and "C NMR studies of N-methyl-substituted hydroxamic acids, RCON(CH,)OH (R = CH,, C,H, and C6Hs), show that the series exhibits &-trans isomerism about the C-N bond. The Z/E ratio increases in the series CH, < C,H, < n-CsH,, < n-C,H,, for a given solvent, indicating that steric interaction betwee
