Abstract

The ^1^H NMR spectra of a series of 2,3‐diaryl‐1,3‐thiazolidin‐4‐ones were measured and the ABX systems due to the heterocyclic ring protons were formally analysed. The chemical shifts and coupling constants were examined in relation to the structures concerned. The effects of S‐oxidation of these compounds on the spectral parameters were investigated. The ^1^H chemical shifts of 3‐benzyl‐2‐phenyl‐1,3‐thiazolidin‐4‐one and 3‐butyl‐2‐phenyl‐1,3‐thiazolidin‐4‐one suggested the presence of a preferred conformation about the NCH~2~ bond.

## Abstract The ^13^C NMR spectra of a series of 2,3‐diaryl‐1,3‐thiazolidin‐4‐ones were measured and the resonance signals produced by the methylene, methine and carbonyl groups of the heterocyclic ring assigned. The variations in their chemical shifts were examined and the influence of __S__‐oxida

Substituents placed on the phenyl rings of 2,3-diphenyl-1,3-thiazolidin-4-one affect the electron density surrounding both the methine proton and the C(2) carbon. These changes are reflected in the differing chemical shifts for these atoms relative to the parent compound. The other carbons in the he

The mass spectral fragmentations of some 2,3-diaryl-l,3-thiazolidin4ones were established by comparing spectra and by using exact mass measurements. The major fragment ions were identified and their relative importances related to substituent effects and bond strengths. Good correlations were observ
