Transmission of substituent effects through extended systems-I. p-Substituted cinnamonitriles

Article abstract of DOI:10.1016/0584-8539(80)80078-X

Infrared data, 13C chemical shifts and ab-initio calculations are reported for a series of p-substituted cinnamonitriles.The i.r. values include intensities for the benzene, ethylene and cyanide vibrations which allow an estimation of resonance effects.The relative importance of the various mechanisms of transmission of electronic effects are discussed.
