Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 87488-84-4, is researched, Molecular C9H7BrN2, about Cyclometalated complexes of platinum(II): homoleptic compounds with aromatic C,N ligands, the main research direction is cyclometalated platinum NMR UV voltammetry; lithiopyrazole cyclocondensation platinum chloride; lithiopyridine cyclocondensation platinum chloride; reduction electrochem cyclometalated platinum.Recommanded Product: 1-(2-Bromophenyl)-1H-pyrazole.
The synthesis of five new homoleptic bis(cyclometalated) Pt(II) complexes, e.g., cis-bis(2-phenylpyridinato)platinum (I), cis-bis[2-(2-thienyl)pyridinato]platinum (II), and cis-bis[1-(2-thienyl)pyrazolato]platinum (III), from trans-PtCl2(SEt2)2 and the lithiated ligands at low temperature is described. All compounds are air-stable, soluble in many organic solvents, and photoreactive in solution under irradiation with visible light. The strong low-energy bands in the electronic spectra in the range from 400 to 450 nm are assigned to metal to ligand charge-transfer (MLCT) transitions from a Pt(5d) orbital to an empty π* orbital of the ligands. Most spectra show a weak absorption superimposed on the low-energy side of the strong MLCT band. This weak absorption is attributed to a singlet-triplet transition of the same type as the strong band. The complexes can be reduced electrochem. in reversible one-electron steps. Oxidation occurs also, but in a completely irreversible manner.
