1.In 2-aryl- and 2-hetaryl-5-trifluoroaeetylpyrroles, the interaction of substituants through the pyrrole ring causes a strong polarization of the molecule.2.The dipole moments of 2-aryl-5-trifluoroaeetylpyrroles are very sensitive to the donor properties of the aryl group and are linearly related to a constants of the para-substituents in the benzene ring (s=3.35).3.The N-vinyl group markedly intensifies the shift of the electrons in the direction of the acceptor as the result of the polarization of the double bond, compensating the positive charge on the nitrogen atom. |
