LONG-RANGE PROTON SPIN-SPIN COUPLING IN DIMETHYL SULFONE,
Abstract
A wide variety of chemical and spectral data suggest that a sulfone group is capable of interaction with an adjacent unsaturated center; however, it seems possible that the mode of this interaction may be significantly different from that of conjugation between first-row elements. To provide evidence pertinent to the problem of conjugation in sulfones, the ability of several oxygen-and sulfur-containing groups to transmit proton spin-spin couplings were compared. Similarity of the C-H coupling constants for dimethyl sulfide and dimethyl sulfone provides evidence that the sulfone is best represented by a structure with predominantly covalent sulfur-oxygen bonds.
