摘要：

The 13C NMR spectra of 17 methyl‐ and ethyl‐substituted tetrahydrofurans and 58 alkyl‐ and aryl‐ substituted 1,3‐dioxolanes are reported. For the cases in which substituents recur, additive substituent parameters are calculated and compared with similar parameters in cyclopentanes and in 6‐membered rings. Considering the conformational flexibility of 5‐membered ring systems, additivity of the parameters is surprisingly good. Copyright © 1979 Heyden & Son Ltd.
