One new copper iodide coordination polymer directed by 4-pyridyl dithioether ligand: Syntheses, structures, and photocatalysis

Qiao Gui-Ying,Li Su-Min,Niu Yun-Yin

One new compound consisting of 1,1-bis(4-pyridylthio)methylene ([Bpytm]) ligand, namely [Bpytm]CuI (1), has been prepared and characterized by IR spectroscopy, solid Uv-visible diffuse reflectance spectrum, and X-ray Powder Diffraction (PXRD). Compound 1 is a 2D MOF and ligand [Bpytm] coordinate with metal ions to form tetrahedral configuration. For compound 1: Crystal system: Monoclinic, Space group: C2/c, a = 13.6671(11), b = 11.6075(11), c = 17.1225(12), α= 90°, β= 93.707(3)°, γ= 90°, V = 2710.6(4) Å3, Z = 8, Dcalc = 2.082 g cm–3. The photocatalytic properties and thermal stability have been researched.

A rapid and efficient solvent-free microwave-assisted synthesis of pyrazolone derivatives containing substituted isoxazole ring

Dawei Zhang,Yumin Zhang,Tianqi Zhao,Jing Li,Yaya Hou,Qiang Gu

An efficient synthesis of 4-substituted pyrazolone derivatives was developed. 4-Substituted pyrazolone derivatives were synthesized in 78–97% yields starting from various 3-substituted isoxazole-5-carbaldehydes, ethyl acetoacetate and hydrazine under microwave irradiation and solvent-free conditions, and were characterized by HRMS , FTIR, 1 H NMR and 13 C NMR spectroscopy. SiO 2 was found to possess favorable catalytic activity and dispersancy for the condensation reaction . The merits of this method include the environmentally friendly reaction conditions, simple operation, broad substrate, satisfied yields and the reuse of the silica. Moreover, the crystal structure of the compound 2-(4-chlorophenyl)-4-((1-(4-chlorophenyl)-5-hydroxy-3-methyl-1 H -pyrazol-4-yl)(3-phenylisoxazol-5-yl)methyl)-5-methyl-1 H -pyrazol-3(2 H )-one ( 5a ) in the monoclinic space group C2/c was presented.
