  Mixed Oxides as Highly Selective Catalysts for the Flash Pyrolysis of Phenacyl Benzotriazole: One-Pot Synthesis of Dibenzazepin-7-one

  摘要：

  The one-pot synthesis of dibenzo[b,d]azepin-7-one (3) was selectively achieved from 1-phenacyl-1,2,3-benzotriazole (1) using the catalytic flash vacuum pyrolysis (cfvp) methodology. Catalysts with the scheelite structure ABO(4) (A = Ca2+, Sr2+, Ba2+ and B = Mo6+, W6+) and fergusonite BiVO4 were explored in this new catalytic reaction. These oxides promoted high conversion of starting material at lower temperatures than those observed for noncatalytic reactions. The chemical nature of A and B cations in the scheelite structure showed a strong influence on the formation toward the desired azepinone. In addition, the catalyst's morphology had a significant influence on the course of the cfvp reaction.

Under ultraviolet (359 nm) excitation, photoluminescence (PL) spectra present the characteristic emission bands at 453 nm and 545 nm which are due to the D 1 2 → F 3 4 and D 1 2 → H 3 4 , 5 transitions, respectively, from Tm3+ ions. Thermoluminescence (TL) measurements were performed with powdered

A centrosymmetric polymorph with O/F disorder, β-BaMoO2F4, has been obtained in several minutes when the reaction mixture was stirred at room temperature in the same medium. Interestingly, we found that the metastable β-BaMoO2F4 transforms into the thermodynamically stable α-BaMoO2F4 in an ambient condition

  AMoO4 (A=Ca, Ba) particles have been successfully synthesized via cyclic microwave-assisted metathetic route in ethylene glycol followed by further heat-treatment. The AMoO4 (A=Ca, Ba) particles were well crystallized after heat-treatment at 400-600 °C for 3 h. The microstructures exhibited fine morphologies with sizes of 0.5-1 and 1.5-2 μm for the CaMoO4 and BaMoO4 particles, respectively. The synthesized AMoO4 (A=Ca, Ba) particles were characterized by X-ray diffraction, scanning electron microscopy. Other spectroscopic properties were also examined using photoluminescence emission measurements and Raman spectroscopy.

  The green phosphor BaMoO4:Tb3+ was prepared by sol-gel method. The effects of doping concentration and sintering temperature on the crystal structure and luminescent properties were investigated by X-ray powder diffraction, scanning electron microscope, UV-visible spectroscopy and photoluminescence spectroscopy. The XRD results showed a pure BaMoO4 phase can be obtained when calcinating phosphor at 900 °C. The photoluminescence spectroscopy spectra exhibited four peaks, the most intense peak of 542 nm can be attributed to 5D4 ® 7F5 transition of Tb3+ and the optimized mol percent of Tb3+ was 0.05. All the results indicated that BaMoO4: Tb3+ could be used as a white-light emitting diodes ultraviolet photoexcitation green phosphors.
