The protonation of some 5-substituted 3-nitro-2-NN-dimethylaminothiophens

Paolo De Maria,   Giovanni Consiglio,   Caterina Arnone  and  Domenico Spinelli  

Abstract

The title reaction has been studied in aqueous perchloric acid. The experimental pKBH+ values obtained according to the Hammett, Bunnett and Olsen, and Yates and Cox methods give good Hammett correlations with ‘thiophen’σ– values. A comparison with the susceptibility constants measured for some series of NN-dimethylanilines has been made and the influence of the hyper-ortho relation in determining the pKBH+ values of the title compounds has been discussed.
