A Solvent‐Free Synthesis of Imidazo[1,5‐a]pyridines Using CCl4 as an Oxidant

Journal of Heterocyclic Chemistry, Volume 63, Issue 8, Page 1288-1299, August 2026.
A solvent‐free synthesis of imidazo[1,5‐a]pyridines (Impys) using CCl4 as an oxidant reagent and DBU as the base is informed. An array of Impys derived from different benzylic, heteroaryl aldehydes and others was synthesized in moderate to good yields.

Benzaldehyde 2,4-dinitrophenylhydrazone

Acta Crystallographica Section C Crystal Structure Communications, 2003
Crystals of the title compound, C(13)H(10)N(4)O(4), were obtained from a condensation reaction of benzaldehyde and 2,4-dinitrophenylhydrazine. The molecule assumes an approximately planar E configuration. Within the dinitrophenyl moiety, the average distance for the aromatic C-C bonds close to the imino group [1.417 (3) A] is appreciably longer than ...

Mechanisms of Oxidation of Benzaldehyde

Nature, 1951
THE early work of Backstrom1 demonstrated the chain character of both the photochemical and the ‘thermal’, that is, dark, oxidation of benzaldehyde to peroxide in the liquid phase. We have studied the kinetics of the thermal reaction in benzene solution at 31° C., and have found it to be catalysed by di-benzoyl peroxide.
