Abstract

The dipole moments of a number of 2-substituted 1,1-dicyanoethylenes have been measured. The moments are explained by a combination of two effects, partial charge separation and compression of the (Chemical Equation Presented) angle. From the data obtained with ω,ω-dicyanofulvenes it is concluded that in compounds (such as I and II) pseudoaromatic structures (such as Ia and IIa) contribute to the ground state of the molecules.
