Ibrahim, Mansur; Malik, Imran; Mansour, Waseem; Sharif, Muhammad; Fettouhi, Mohammed; El Ali, Bassam published the artcile< Efficient N-heterocyclic carbene palladium(II) catalysts for carbonylative Suzuki-Miyaura coupling reactions leading to aryl ketones and diketones>, Recommanded Product: 5-Bromo-1-methyl-1H-imidazole, the main research area is palladium heterocyclic carbene pyridine complex catalyst preparation; aryl ketone diketone preparation; iodide aryl boronic acid palladium catalyst carbonylative Suzuki Miyaura.
New N, N’substituted imidazolium salts and their corresponding diiodopyridinepalladium(II) complexes I [R = CN, OMe] were successfully synthesized and characterized. Reactions of palladium iodide with the newly synthesized N, N’-substituted imidazolium iodides in pyridine afforded the corresponding new palladium-N-heterocyclic carbene pyridine complexes I in high yields. The new palladium(II) complex I [R = OMe] was characterized by single crystal X-ray diffraction anal. The Pd(II) ion was bonded to the nitrogen atom of the pyridine, the carbon atom of the NHC carbene ligand and two trans iodides resulting in distorted square planar geometry. The carbonylative Suzuki-Miyaura coupling reaction of aryl iodides with aryl boronic acids afforded aryl ketones II [R1 = H, CN, C(O)Me, OMe; R2 = H, OMe, COOH, etc.] and diketones III [R3 = H, CN, OMe] using palladium-N-heterocyclic carbene pyridine complexes.
Journal of Organometallic Chemistry published new progress about Aryl iodides Role: RCT (Reactant), RACT (Reactant or Reagent). 1003-21-0 belongs to class imidazoles-derivatives, and the molecular formula is C4H5BrN2, Recommanded Product: 5-Bromo-1-methyl-1H-imidazole.
