Notizen:
The 1H NMR 270-MHz spectra of substituted 2-phenylthiazolidines were recorded and the substituent-induced chemical shifts (SCS) of the benzylic proton plotted against σ, the correlation coefficient being 0.801 and -ρ = 10.29 Hz. Halogens show deviations in the SCS plots. When the halogen-substituted derivatives are omitted, the correlation with σ is greatly improved. The applicability of dual-substituent correlations using Swin-Lupton parameters (F and R) and Taft's σ1, σR parameters has been studied.
