Studies on Tertiary Amine Oxides. XVIII. On the Reduction of 1-[ (1-Oxido-2-pyridyl) methyl] pyridinium Salt.

Abstract

Modified King reaction of 2-picoline 1-oxide gave pyrido [1', 2' : 3, 4] imidazo [1, 2-α] pyridinium iodide instead of 1-[ (1-oxido-2-pyridyl) methyl] pyridinium iodide (Ia). Selective reduction of N-oxide or pyridinium group of Ia was investigated.
