Abstract
Several 4-(substituted) -Hantzsch esters upon oxidation with bentonite supported metallic nitrates (Ag+, Fe+3, Cu+2, Co+2) under mild conditions, afforded the corresponding pyridines. As result of a comparative study, a synergism between the nitrate and the metallic ions with the TAFF support is suggested.
