The σ-Constants of the Cyano Group

Abstract

Despite the importance of the cyano group as a substituent group of organic compounds, relatively few data are available for the quantitative evaluation of it6 electrical effect on organic reactions. Thus, while Hammett's compilation includes a value (based on a single reaction) for the u- (substituent) constant of the m-cyano group, none is given which applies to compounds other than anilines or phenols for the p-cyano group.
