Abstract
It is shown that in the reaction of 2-vinylpyridinium quaternary salts with methylammonium sulfite under isomerization recyclization conditions a water molecule adds initially to the double bond of the vinyl substituents, after which the resulting carbinols undergo recyclization to N-alkylaniline derivatives. The reaction is accompanied by a parallel process involving dealkylation of the pyridine ring.
