| Abstract: | Carbon-13 chemical shifts (substituents effects, variations of shielding and deshielding related to the magnitude of n.π or π.π interactions) not only confirm the non-planar conformation of ketimines of the benzalaniline type, but provide torsional angles of the aromatic rings. Carbon-13 chemical shifts of dibenzo[b,f] diazocines[1,4] confirm the tub-like conformations and the presence of n.π and π.π interactions. |
