Synthesis of 2-Arylpyridines and 2-Arylbipyridines via Photoredox-Induced Meerwein Arylation with in Situ Diazotization of Anilines

We report herein a sustainable method for the preparation of 2-arylpyridines through C-H arylation of pyridines using in situ formed diazonium salts (from commercially available aromatic amines) in the presence of a photoredox catalyst under blue light-emitting diode (LED) irradiation. The reaction is tolerant to a wide range of functional groups (e.g., halogen, nitrile, formyl, acetyl, ester). Applications to the C-H bond arylation of bipyridine ligands is also presented.

A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 108-47-4

Critical Behavior of Hydrogen Bonds Observed in High-Pressure Nuclear Quadrupole Resonance Studies

The high-pressure effect on NQR frequencies of 35Cl nuclei has been studied for the complexes of pentachlorophenol with nitrogen bases at 77 K.The correlation between the value of pressure frequency coefficient and the degree of proton transfer has been found.In the vicinity of the critical point of the hydrogen bond (complexes with 50percent proton transfer) the anomaly of the pressure frequency coefficient has been observed.

Cationic heteroconjugation constants in the OHN+ and NHO+ systems in propylene carbonate: Dependence on difference in basicity

Cationic heteroconjugation equilibria of more than ninety systems consisting of substituted pyridines, their N-oxides, and trimethylamine N-oxide, i. e., in systems with “mixed” hydrogen bridges of type OHN+ (NHO+) were studied in propylene carbonate. Both experimental systems without proton transfer, BH+/B1, and those with proton transfer, B1H+/B, were explored. The stability of the “mixed” hydrogen bridges, OHN+ (NHO+), is compared with that of the OHO+-type bridges. The influence of the difference in basicity of the conjugate base of the proton donor and the proton acceptor on the presence of the proton transfer equilibria, and, consequently, the possibility of determination of the cationic heteroconjugation constant values is discussed.

Effect of Basicity, Steric Hindrance and Bonding Ability of Nitrogen Bases in the Formation of Adducts with Some Methyl-substituted N-Phenylbenzohydroxamates of Nickel(II)

The formation of two types of octahedral base adducts of the Ni(II) complexes of some sterically hindered N-arylbenzohydroxamic acids has been substantiated from spectral studies.The 1:1 and 1:2 base adducts have been isolated and characterised on the basis of elemental analyses, magnetic moment measurements, cryoscopic determination of molecular weights and visible absorption spectra.While the bis-adducts are monomeric octahedral complexes, the mono-adducts attain octahedral stereochemistry through dimerisation.

Iron-catalyzed direct alkenylation of 2-substituted azaarenes with N -sulfonyl aldimines via C-H bond activation

A novel iron-catalyzed alkenylation of 2-substituted azaarenes through sp3 C-H bond activation has been developed. A favorable E2-elimination is proposed as a key step to cleavage of C-H and C-N bonds for the construction of a C=C bond in high stereoselectivity. This transformation represents an efficient way to synthesize 2-alkenylated azaarenes from simple starting materials.
