³⁵Cl n.q.r. of fifty-nine molecules containing the S—Cl bond

Abstract

The 35Cl n.q.r. frequencies of eleven sulphinyl and sulphenyl chlorides, nine substituted alkyl sulphonyl chlorides, five halo and oxysulphonyl chlorides, four N-substituted N-sulphonyl chlorides, ten halobenzene sulphonyl chlorides, six methylbenzene and p-methoxybenzene sulphonyl chlorides, six nitrobenzene sulphonyl chlorides and seven carboxy and sulphone substituted benzene sulphonyl chlorides are reported for 77 K. The frequencies are interpreted in terms of the sulphur orbital electronegativity, the inductive effects of substituents and possible dπ orbitals on sulphur. The most coherent explanation is that the —SO2— group behaves like the pseduo-united atom germanium.
