Activation of weak organic bases: the alkylation of NN-disubstituted sulphonamides
Abstract
Methylation of the NN-disubstituted sulphonamides (IIIa,b) by dimethoxycarbonium hexachloroantimonate (II) gave the crystalline N-methylated salts (IVa,b), which afforded methyl amine derivatives on acid hydrolysis.
