Notes:
77Se N.m.r. spectra of 4,4′-disubstituted diphenyl selenides have been obtained. The chemical shifts could be correlated with substituent constants of the Hammett type or with Swain and Lupton two-parameter equations. No correlations were observed between these 77Se shifts and the 13C shifts of the CH2 group of 4,4′-disubstituted diphenylmethanes, the latter shifts showing no correlation with substituent constants. On the other hand linear correlation was observed between the 77Se shifts of the 4,4′-disubstituted diphenyl selenides and the 1H shifts of the CH2 group of the diphenylmethanes, the 13C shifts of their 1-carbons and the 19F shifts of 4-substituted fluorobenzenes.
