Application of 15804-19-0, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 15804-19-0, Quinoxaline-2,3(1H,4H)-dione, introducing its new discovery.
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
2,2?-(Alkanediyl)-bis-1H-benzimidazoles (simple and mixed) with variable methylene spacers were synthesized in excellent yields with aqueous fluoroboric acid (45%) (0.1 ml) as catalyst under solvent-free conditions. Their optimized structures were obtained using DFT calculations where it was seen that the s-trans orientation of the two imidazole rings was preferred for all types of bis-benzimidazole systems. The X-ray crystal structure of one such bis-benzimidazole further corroborated this fact. Finally, photophysical studies were carried out to get insight into the fluorescence characteristics of the newly synthesized bis-1H-benzimidazoles. ARKAT USA, Inc.
