One Step Conversion of Heteroaromatic-N-Oxides to Imidazolo-Heteroarenes
摘要:
[GRAPHICS]Various pyridine-, quinoline-, isoquinoline-, and pyrimidine-N-oxides were converted to their corresponding alpha-imida-zoloheteroarenes in good yield by treatment with. sulfuryl diimidazole in nonpolar solvents at elevated temperatures.

nanoparticle encapsulation to fabricate water-soluble nanocatalysts (NCs) for aqueous cross-couplingreactions. To achieve this goal, three types of N-heterocycliccarbene (NHC)–palladium (Pd) complexes (i.e., 1b, 2b, and 3b) with the chemical formula [PdL(CH3CN)Cl]PF6 (where L is a bidentate pyridine- or pyrimidine-bearing NHC ligand) have been synthesized, and their structures were characterized by NMR spectroscopy

Efficient and solvent-free copper-catalyzed N-arylations of imidazoles with aryl and heteroaryl halides have been demonstrated. In the presence of CuBr, 2-aminopyrimidine-4,6-diol, and TBAF (n-Bu4NF), a variety of imidazoles underwent the N-arylation reaction with aryl and heteroaryl halides smoothly in moderate to excellent yields. Noteworthy is that the reaction is conducted under solvent-free conditions
