Abstract
Application of the novel solvent-dependent pKa method for the construction of Brønsted-type plots to the sulfonyl transfer reaction with phenoxide nucleophiles, finds the pKa's of aryloxides lower than those of the p-nitrophenoxide leaving group on separate lines, whereas nucleophiles of greater pKa fall on a common line, contrasting with the observed behaviour when using the traditional method.Keywords
