TriphenylamineвЂ“Benzimidazole Derivatives Synthesis. SYNTHESIS AND CHARACTERIZATION OF NOVEL BENZIMIDAZOLE.
Polycyclic benzimidazole derivatives, an important class of compounds in organic electronics and photovoltaics, were prepared using a solvent-free вЂњgreenвЂќ process based on heating carboxylic acid anhydrides and arylene diamines in the presence of zinc acetate in the solid state.. Green Synthesis of Benzimidazole Derivatives: An Overview of Bulk Drug Synthesis Article (PDF Available) in International Journal of PharmTech Research 8(9):60-68 В· January 2016 with 1,432 Reads.
Benzimidazole and its derivatives are used in organic synthesis and vermicides or fungicides as they inhibit the action of certain microorganisms. Examples of benzimidazole class fungicides include benomyl, carbendazim,. W e report the synthesis of benzimidazole derivatives using zinc triflate as an efficient catalyst. One-pot synthesis of 2-substituted benzimidazole derivatives from o-phynelyenediamine and substituted aldehydes were developed under zinc triflate in ethanol solvent at reflux temperature..
“2-Mercaptobenzimidazole Derivatives Synthesis and”.
Several researchers reported a synthesis of benzimidazole derivatives, but in our present study we synthesized the benzimidazole derivatives by using ammonium salts as catalysts, which were inexpensive and decreased the reaction time, with very good yields. This method could be easily practiced in laboratories within the stipulated time..
Imidazole and Benzimidazole Synthesis is a comprehensive survey of the known methods of syntheses and ring modification. It brings together the multitude of synthesis of the imidazole ring in a systemic way interms of specific bond formation, and recommends the most attractive synthetic approaches. It also collects non-ring-synthetic approaches to classes of compounds such as nitro-, вЂ¦. Several researchers reported a synthesis of benzimidazole derivatives, but in our present study we synthesized the benzimidazole derivatives by using ammonium salts as catalysts, which were inexpensive and decreased the reaction time, with very good yields. This method could be easily practiced in laboratories within the stipulated time.. enhanced antimicrobial activity, a series comprises 2-substituted-5-nitro benzimidazole derivatives were synthesized. Investigation of antimicrobial activity of the compounds was done by disc diffusion method using Gram-positive ( S. aureus ,.
