Design and preparation of [4,4′-bipyridine]-1,1′-diium trinitromethanide (BPDTNM) as a novel nanosized ionic liquid catalyst: application to the synthesis of 1-(benzoimidazolylamino)methyl-2-naphthols

Abstract

A novel bifunctional nanosized molten salt catalyst promoted the synthesis of 1-(benzoimidazolylamino)methyl-2-naphthols.

Rationally Designed Manganese-Based Metal–Organic Frameworks as Altruistic Metal Oxide Precursors for Noble Metal-Free Oxygen Reduction Reaction

“…59 On coordination of BPY with the metal ion, the planar ring of BPY is distorted, resulting in the lowering of π-electron delocalization within the ring, thereby increasing the double-bond character of π bonds, and shows a positive shift in FT-IR bands. 60 The absorption band observed at 554 cm −1 in both Mn-SKU-1 and Mn-SKU-2 may be assigned to the vibration of the Mn−O bond. 61 Thermogravimetric analysis (TGA) shows an incremental mass loss of 8.5% at 180−200 °C for Mn-SKU-1 and can be accounted for the loss of two coordinated H 2 O molecules (Figure S3a).…”

“…Interestingly, the coordination of BPY to Mn through the nitrogen atoms is indicated by the positive shift of the CN and CC ring stretching frequencies in Mn-SKU-2 (∼1606 and 1500 cm –1 ), which is lower in the free BPY ligand (1587 and 1484 cm –1 , respectively) . On coordination of BPY with the metal ion, the planar ring of BPY is distorted, resulting in the lowering of π-electron delocalization within the ring, thereby increasing the double-bond character of π bonds, and shows a positive shift in FT-IR bands …”

Surface engineering of a triboelectric nanogenerator for room temperature high-performance self-powered formaldehyde sensors

“…4a, which are in good agreement with the results obtained in previous studies. 51,52,58 The characteristic IR bands of bpy and PMA were found to persist in bpy–PMA except for some minor differences (Fig. 4a), which proved that bpy was successfully loaded into the PMA matrix.…”

L‐lysine‐Pd Complex Supported on Fe3O4MNPs: a novel recoverable magnetic nanocatalyst for Suzuki C‐C Cross‐Coupling reaction

“…[73][74][75][76][77][78][79] In this sense, the combination of the magnetic property of the magnetic nanoparticles (MNPs) and the molecular recognition of a specific organic structure exposed their distinct advantages. [80][81][82][83][84][85][86] The magnetic nanoparticles can be well dispersed in the reaction mixtures in the absence of magnetic field providing large surface area for a readily access of the substrate molecules. [7,23] On the other hand, the organic coat, owing catalytic sites along with structural approach, improves the catalytic activity of such nanocomposite.…”
