Abstract

Abstract The NMR spectra of a number of 2, 4-disubstituted 1, 3-dioxolanes have been recorded and the proton chemical shifts and coupling constants derived from complete spectral analysis. Vicinal coupling constants were found to be dependent on the substituent at C-4 and this effect is more pronounced for J (trans) of the C-4-C-5 fragment. These coupling constants also indicate a homogeneous behaviour within a series with either a ...
