Dipole moments and configuration of imidoyl chlorides

Abstract

The electric dipole moments of six aromatic imidoyl chlorides have been measured in benzene solution. The results allow the Z-configuration to be confirmed unambiguously by a graphical method, irrespective of possible variations of the bond moments used. A more exact determination of these bond moments from experimental data is not feasible, the common values hitherto used being however, quite acceptable. Hence the CN bond may not be as highly polarizable as was expected.
