Reactions of dimethyl sulphate with amines-Structural elucidation and thermochemical studies

Abstract

Reactions of dimethylsulphate with pyridine, <img src='/image/spc_char/alpha.gif' border=0>-, <img src='/image/spc_char/beta.gif' border=0>-, <img src='/image/spc_char/gamma2.gif' border=0>-picolines, quinoline, N-propylamine, Nsbutylamine, dimethylamine and diethylamine yield new products of the type Me₂OSO₃ Amine. These products have been characterized on the basis of elemental analysis, molar conductances, molecular weights, thermochemical and spectroscopic data, which indicate the transfer of methyl group from dimethyl sulphate to nitrogen of amine giving rise to ionic products of the formula (Amine CH₃)⁺ (CH₃SO₄)^-.
