Notes:
The 13C n.m.r. spectra of complexes between o-chloranil and aromatic electron donors were studied. Complexation leads to a general diamagnetic shift of the 13C n.m.r. signals for the acceptor (o-chloranil), but for signals from the 13C nuclei in the donors both diamagnetic and paramagnetic shifts are found.These phenomena are thought to be the result of competing anisotropy and charge-migration effects. Charge migration in o-chloranil complexes appears to be more important than in corresponding 1,3,5-trinitrobenzene complexes.
