Étard Reaction: Ii. Polycyclic Aromatic and Heterocyclic Compounds

Abstract

Polycyclic aromatic compounds can, in a nuniber of cases, be oxidized with chroniyl chloride, whereas heterocyclic compounds are unaffected.

One Pot Synthesis of Formyl Phenyl Terpyridine: A Simplified Synthesis

“…Variety of reagents convert methyl group to aldehyde. Methods like Etard reaction, chromyl chloride oxidation and oxidation with PCC involve multistep reactions for conversion [8][9][10][11] . Cerium and Iridium catalyzed reaction can oxidize methyl group attached to aromatic group like benzene [12][13][14][15] but is not successful in oxidizing methyl groups attached to heterocyclic rings.…”
