A green approach for the synthesis of N-alkylthiomethyl benzimidazoles 2 (R=CH 3, C 2 H 5, CH 2 Ph) under different conditions has been developed from N-alkylchloromethyl benzimidazole (i.e., CH 3, C 2 H 5, CH 2 Ph) 1 by reaction with thiourea by physical grinding, or by using green solvents like ethanol and PEG, or by using microwave irradiation : S. Srinivas Rao, Ch. Venkata Ramana Reddy, P. K. Dubey. Benzimidazole, a heterocyclic aromatic organic compound consisting of a fusion of benzene and imidazole, in an extension of the well-elaborated imidazole system, has been used as a carbon skeleton for N -heterocyclic carbenes, usually used as ligand for transition metal complexes. Pharmacological compounds of benzimidazole derivatives are potent inhibitors for a variety of .

Lacey Benzimidazoles represent the only class of truly broad-spectrum anthelmintics, how- ever, they also show activity against fungi and mammalian cells.
This raises the ques- tion as to why benzimidazoles can selec- tively kill helminths and yet exhibit little or no mammalian by: Pages in category "Benzimidazoles" The following 89 pages are in this category, out of 89 total. This list may not reflect recent changes ().
INTRODUCTION: Benzimidazoles and its derivatives represent one of the most biologically active classes of compounds, possessing a wide spectrum of. Imidazoles, benzimidazoles, imidazolines, imidazolidines, and related carbenes are classes of heterocyclic compounds possessing unique chemical and physical properties.
Tremendous advances in imidazole chemistry have been made in the decade sinceand are manifested in the large body of the literature related to imidazole and its analogs. imino-ethers, (c) carbonyl compounds and (d) nitriles to yield differently substituted benzimidazoles.
