The chromatography of benzimidazoles

Journal of Chromatography A, 1973
Summary The thin-layer chromatography of a series of mono- and bis-benzimidazoles has been studied in order to determine the influence of substituents. Results for the gas-liquid chromatography of 2-alkyl-substituted benzimidazoles and their silyl derivatives show that a quasi-exponential relationship exists between retention time and the carbon ...

Selective Synthesis of 2-Substituted and 1,2-Disubstituted Benzimidazoles Directly from Aromatic Diamines and Alcohols Catalyzed by Molecularly Defined Nonphosphine Manganese(I) Complex.

Journal of Organic Chemistry, 2018
Herein, we present a selective synthesis of 2-substituted and 1,2-disubstituted benzimidazoles by acceptorless dehydrogenative coupling of aromatic diamine with primary alcohols. The reaction is catalyzed by a phosphine-free tridentate NNS ligand-derived
