Journal ArticleDOI
Direct amide bond formation from carboxylic acids and amines using activated alumina balls as a new, convenient, clean, reusable and low cost heterogeneous catalyst
TL;DR: In this paper, activated alumina balls (3-5 mm diameter) were used for amide synthesis from carboxylic acids and amines under neat reaction conditions that produce no toxic by-products and has the advantages of being low-cost, easily available, heterogeneous, reusable and environmentally benign with no troublesome/hazardous disposal of the catalyst.
Journal ArticleDOI
Synthesis of 2-alkyl substituted benzimidazoles under microwave irradiation: Anti-proliferative effect of some representative compounds on human histiocytic lymphoma cell U937
TL;DR: In this article, the synthesis of 2-alkyl substituted benzimidazoles under microwave irradiation using 62% aqueous hexafluorophosphoric acid (10 mol%) as catalyst was presented.
Journal ArticleDOI
Unraveling the molecular recognition of “three methylene spacer” bis(benzimidazolium) moiety by dibenzo-24-crown-8: pseudorotaxanes under study
TL;DR: The difference in the extent of threading of various "three methylene spacer" bis-benzimidazolium moieties based on differences in aromatic methyl substituent positions and anions through the macrocycle dibenzo-24-crown-8 is unveiled.
Journal ArticleDOI
An efficient and versatile synthesis of 2, 2'-(alkanediyl)-bis-1H-benzimidazoles employing aqueous fluoroboric acid as catalyst: density functional theory calculations and fluorescence studies
TL;DR: Alkanediyl bis-1H-benzimidazoles with variable methylene spacers were synthesized in excellent yields with aqueous fluoroboric acid (45%) (0.1 ml) as catalyst under solvent-free conditions as mentioned in this paper.
Journal ArticleDOI
Bis(benzimidazolium)methane salts: A potential guest for dibenzo-24-crown-8 towards [2]pseudorotaxanes
TL;DR: In this article, the threading of bis(benzimidazolium) methane moieties with DB24C8 at 35°C (room temperature) was investigated and the presence of threaded complexes was determined by 1H NMR and also supported by high resolution mass spectrometry and B3LYP/6-31G++ calculations.
