A Green Lindqvist-Type POM/TEMPO/H₂O₂ Ternary Catalytic System for the Selective Oxidation of Hantzsch 1,4-Dihydropyridines (1,4-DHPs) to Pyridines

Molecules
Pyridine derivatives are prepared via the dehydrogenative aromatization of 1,4-dihydropyridines (1,4-DHPs). Among these methods, stoichiometric catalysis with high waste and electrochemical oxidation with less productivity are limited in their use ...
