Abstract
The complete carbon-13 nmr spectra of 16 alkylated 2,5-dihydrothiophenes and 10 sulfones derived from them are reported. No significant interactions between C-2 substituents and C-5 are noted and stereochemical determinations based on this γ effect are not possible. On oxidation to the sulfones, C-2 and C-5 are dramatically deshielded but C-3 and C-4 are shielded. A possible explanation for this effect is presented.
