Bamers to rotation about the partial double C-N' bond were determined from line shape analysis of 'H and I3C dynamic NMR spectra of N',N'-dimethyl-NZ-substituted phenylacetamidines with twelve different substituents on the phenyl ring. The values of AGGc are 51.2-58.7 kJ mol-' and the correlation wi
Rates of rotations about the C-N' partial double bond in a series of six N',N' penta-and six N',N'-hexa-methylene-Nz-substituted-phenyformamidines were determined from 13C DNMR line shape analysis. Electron accepting substituents at the phenyl ring increase the barrier to rotation, and electron don
