Abstract

³³S and ¹⁷O chemical shifts of substrates CH₃SO₂Y for Y = Br, I, SeC₆H₄ and p-CH₃C₆H₄SO₂Y for Y = F, Cl, Br, I are reported. Evidence is provided for the existence of n → σ^* conjugative interactions between the oxygen lone-pair molecular orbitals of the sulfonyl group and the vacant σ^* (S-Y) MO. The trend of oxygen chemical shifts is rationalized in terms of conjugative interactions and electronegativity effects which may operate in the same or in opposite directions. © 1990.
