Halder, S in [Halder, Samiran] Charuchandra Coll, Dept Chem, 22 Lake Rd, Kolkata 700029, India published Vanadyl Acetylacetonate-Copper (II) Trifluoro Methane Sulfonate Catalyzed Eco-friendly Synthesis of Substituted Benzimidazoles in Aqueous Media in 2020.0, Cited 68.0. SDS of cas: 93-02-7. The Name is 2,5-Dimethoxybenzaldehyde. Through research, I have a further understanding and discovery of 93-02-7.
Various substituted benzimidazoles have been successfully synthesized in aqueous medium by developing VO(acac)(2)-Cu(OTf)(2) catalytic system. A green synthetic protocol has been created in presence of water and cetyltrimethyl ammonium bromide (CTAB) system in an organic solvent free condition. This chemoselective cyclocondensation cumoxidation process occurred in aqueous media. In this suitable method easily synthesized 2-Substituted benzimidazoles with good yields and no 1,2-disubstituted by-products were noticed. Excellent yields, environmentally benign and mild reaction condition, easy purification of the desired products are the main attractive features of this newly devised method. [GRAPHICS]
