2, 3-Dichloro-5, 6-dicyano-1, 4-benzoquinone (DDQ) is the most widely used quinone with a
high reduction potential, and it commonly mediates hydride transfer reactions and shows …

Great advances in elucidating molecular structures allow the precise determination of the
interactions between a protein and a therapeutic agent. Enzyme inhibitors are used as a …

A new, convenient method for the syntheses of 2-substituted benzimidazole and
benzothizole is described. Short reaction times, large-scale synthesis, easy and quick …

A practical and convenient synthetic method has been developed for the facile synthesis of
1, 2-disubstituted benzimidazoles, 2-substituted benzimidazoles and 2-substituted …

Direct one-step synthesis of various benzimidazoles from phenylenediamines and
aldehydes is described using air as the oxidant. The salient features of this method include a …

Addition of oxone® to a mixture of a 1, 2-phenylenediamine and an aldehyde in wet DMF at
room temperature results in rapid formation of benzimidazoles under very mild conditions …

The Schiff base derived from the condensation of o-aminophenol with benzaldehydes was
induced to undergo oxidative cyclization in the presence of DDQ. The resulting 2 …

Here we demonstrate the synthesis of benzimidazoles through the coupling of 1, 2-
phenylenediamine with aldehydes by using Co (OH) 2 and similarly CoO (II) as efficient …

In this study, SO3H@ zeolite-Y was synthesized by the reaction of chlorosulfonic acid with
zeolite-NaY under solvent-free conditions, which was then supported by Fe3O4 …

A new catalytic oxidation system using catalytic amounts of 2, 3‐dichloro‐5, 6‐dicyano‐1, 4‐
benzoquinone (DDQ) and tert‐butyl nitrite with molecular oxygen serving as the …
