The Formation of Alkenes by the Thermal Elimination Reaction of <i>N</i>-Methyl-4-Alkoxypyridinium Iodides. I. Scope of the Reaction

Abstract

Twenty-one 4-alkoxypyridines and their corresponding N-methyl-4-alkoxypyridinium iodides have been prepared and the latter pyrolyzed at temperatures ranging from room temperature to 185° to give the olefins derived from the alkyl moiety in high yields.
