Very fast and efficient synthesis of some novel substituted 2-arylbenzimidazoles in water using ZrOCl2·nH2O on montmorillonite K10 as catalyst

Simple, Efficient, and Applicable Route for Synthesis of 2-Aryl(Heteroaryl)-Benzimidazoles at Room Temperature Using Copper Nanoparticles on Activated Carbon as a Reusable Heterogeneous Catalyst

“…Albeit several reports [25][26][27][28][29][30][31][32][33], the direct condensation of o-aryldiamines and aromatic aldehydes at room temperature is less developed because as previously reported [36] this superficially simple reaction is a complex sequence of competing reactions and leads to the formation of a complex mixture of products containing 1,2-disubstituted benzimidazoles and 1,2-disubstituted benzimidazolines as main byproducts. Moreover, most of the catalysts have been used for this purpose are not recoverable and destroyed in the work-up procedure.…”

Novel dibenzo-18-crown-6 ether functionalized bis-benzimidazole derivatives: synthesis and antifungal evaluation

“…A literature survey reveals that synthesis of benzimidazole derivatives can be accomplished by using SiO 2 -OPO 3 H [24], tosic acid on silica gel [25], ZrOCl 2 ÁH 2 O [26], microwaves [27], Cu nanoparticles [28], Cu(OTf) 3 [29], and Au catalyst [30]. Considering the remarkable pharmaceutical significance of these diversified structural entities, there emerges a need to develop greener methodologies for their efficient synthesis.…”

$$\hbox {C}_{32}\hbox {, Si}_{32}$$ C 32 , Si 32 and $$\hbox {B}_{16}\hbox {N}_{16}$$ B 16 N 16 as anode electrodes of Li-, Na- and K-ion batteries: theoretical examination

“…A rechargeable battery is a kind of electronic battery that has many electro-chemical cells and it can be recharged several times. The rechargeable batteries have been used in starter of cars, consumer devices and battery reservoir centres [1][2][3][4][5][6]. In a lithium-ion battery (LIB), as performance kind of rechargeable cells, there are two processes: in the charging process the lithium ions transfer from the positive to negative electrode and in the discharge process the motion of lithium ions is the reverse of the charge process [7][8][9][10][11][12].…”
