“…The detailed NMR data have been published 22,23 but we shall mention here briefly only some interesting results concerning simple Hammett-type correlations; a more complicated treatment (DSP) can be found in the references cited. 22,23 Linear correlation of 15 N chemical shifts with Hammett substituent constants in the silyl derivatives of benzhydroximic acids studied confirms the hydroximic structure, as the slope (TMS derivatives; b = 7.73, n = 12, r = 0.966) is intermediate between those found in analogous correlations for N,N-dimethylbenzamides (C-N; b = 3.79, n = 12, r = 0.951) and benzonitriles (CN; b = 10.5, n = 7, r = 0.993).…”
