A Dipole-moment study of N-(α-cyanobenzylidene)alkylamines and N-(α-cyanobenzylidene)anilines

Dipole Moments of Compounds Containing Double Bonds

“…With some other azomethines, the dipole moment of the equilibrium mixture was calculated using the NMR results and was in agreement with experiment 91 . In the azomethines 20 the dipole moments are more telling for the configuration, due to the presence of the polar CN group 92 : only the E configuration is present.…”
