Abstract:  Infrared spectral data of seven aromatic diphenylketene-N-phenylimine derivatives are reported. Integrated absorption intensities of vas(CCN) of ketenimines with vas(XYZ) of typical heterocumulenes are compared and correlated with  σ-substituent constants. It has been found that the CCN group of ketenimines studied is electron-releasing.
