Notes:
Chemical shifts of the olefinic carbons of ω-substituted 1-pentenes and 1-butenes and the aromatic carbons of phenylethanes and phenylpropanes have been measured. Correlations with various substitutent constants, electronegativities, NMR data from related chemical systems and calculated electrical fields were evaluated. Although the pattern of results is quite consistent with expectations for a field-induced shift of π-electron density, simple correlations of high statistical precision are not found. The general problem of correlating substitutent effects with reactivity and NMR shifts is discussed.
