Notes:
The 13C NMR spectra of 20 compounds belonging to several types of monocyclic sultones and related ‘carbyl sulphates,’ including a series of fluorinated β-sultones (1,2-oxathietane 2,2-dioxides), are reported. Chemical shift increment systems with n-alkanes as reference molecules are established for non-fluorinated sultones: they show a much less pronounced deshielding effect on the carbon α to oxygen in β-sultones than in the other series. Chemical shifts for the parent β-sultone, predicted in two ways (linear or cyclic model compound), are found to be almost consistent with a purely additive scheme. In fluorinated β-sultones the α-substituent increments relative to perfluoroethanesultone are also derived.
