4,4′-Bipyridine (abbreviated to 4,4′-bipy or 4,4′-bpy) is a bipyridine which is mainly used as a precursor to N,N′-dimethyl-4,4′-bipyridinium [(C5H4NCH3)2]2+, known as paraquat. This species is electroactive, and its toxicity arises from the ability of this dication to interrupt biological electron transfer. Because of its structure, 4,4′-bipyridine can bridge between metal centres to give coordination polymers 4,4′-Bipyridine can also mediate electronic effects between two paramagnetic metal centers.
4,4’-Bipyridine is also known as 4,4’-bipy is a bipyridine which is mainly and aptly used as a precursor to N,N′-dimethyl-4,4′-bipyridinium [(C5H4NCH3)2]2+ is called as paraquat. This species tends to be electroactive and its toxicity basically arises from the ability of this dictation to interrupt biological electron transfer. 4,4’-Bipyridine act as a bridge between metal centres to give coordination polymers only because of its structure. 4,4’-Bipyridine is also believed to mediate electronic effects between two paramagnetic metal centres.
The preparation of this complex organic compound relates to the novel bifunctional nanosized ionic liquid catalyst [4,4′-bipyridine]-1,1′-diium trinitromethanide (BPDTNM) is basically designed, synthesized and characterized by using FT-IR spectra, IH and 13C NMR spectra, scanning electron microscopy(SEM), X-ray diffraction patterns (XRD), high resolution transmission electron microscopy (HRTEM), derivative thermogravimetry (DTG) analysis, HPLC-mass spectroscopy and basically the differential thermal analysis (DTA).
The synthesized nanosized catalyst is then successfully applied to the synthesis of 1-(benzoimidazolylamino)methyl-2-naphthol derivatives through a straightforward one-pot three-component condensation reaction under mild and solvent-free conditions of 2-aminobenzimidazole, 2-naphthol, and a wide range of aromatic aldehydes.
4,4’-Bipyridine is basically used in the transition metal complex catalyst chemistry for uniform polymerization, in luminescence chemistry and in spectrophotometric analysis.
It is a ligand, forming a square planar geometry. It's versatile structure precisely the crystal structure finds a wide application in coordination chemistry.
It also helps in the data processing of the Raman spectra recorded during the slow sorption of 4,4’-Bipyridine in acidic HnZSM-5 (n = 3, 6) zeolites. This provides a specific Raman spectrum of N,N‘-diprotonated dication 4,4‘-bpyH22+ as unique species which is generated in the void space of the acidic ZSM-5 zeolites.
