The epoxidized soybean oil methyl ester was prepared by a non⁃solvent method under a mild condition using molybdenum polyoxometalates as catalysts.The epoxy soybean oil methyl ester with an acid value of 0.58 mg (KOH)/g and an epoxy value of 3.73% could be obtained using a H2O2:C=C of substrate molar ratio of 1.5 with adding 1.5% catalyst [(C2H5)4N]4Mo8O26 when 20 g soybean oil methyl ester was epoxidized at 55 ℃ for 5.0 h. The method has the advantages that the catalyst is easy to be separated and the post⁃treatment is simple. Moreover, the product does not contain inorganic acid, which avoids the influence of inorganic acid on the analysis and treatment of product.

The research progress of rare earth metal-mediated group transfer polymerization (REM-GTP) is reviewed. The main features of this polymerization method, the polymerization mechanism and its application in the polymerization of vinyl phosphonates and other nitrogencoordinating monomers are introduced. The application prospect and developing direction of this kind of polymerization method are also forecasted.

3-Methoxythioxanthone was synthesized, and the structure is identified by ¹H NMR, ¹³C NMR, IR and HRMS spectra. The UV-Vis absorption spectra of 3-Methoxythioxanthone shows that it absorbs near the purple light (380 nm) in the visible range and is a visible light photosensitizer. 3-Methoxythioxanthone was applied to the Aza-Henry reaction of 2-phenyl-1,2,3,4-Tetrahydroisoquinoline and Nitromethane. Under the irradiation of purple LED, the photosensitizer with a molar fraction of 5% allowed the reaction to be isolated in a yield of 84% within 6 h. According to the experimental results, the mechanism of photocatalytic reaction of AzaHenry was proposed. The photosensitizer could transfer energy to produce singlet oxygen under the illumination, and singlet oxygen promoted the Aza-Henry reaction.

This article reported the method about the synthesis of a foursubstituted diphenyl phosphine oxide type allene compounds. In the solvent system of anhydrous triethylamine, 1,1-diphenylhept-2-yn-1-ol reacted with chlorodiphenylphosphine in anhydrous tetrahydrofuran, it got the desired product (1,1-diphenylhepta-1,2-dien-3-yl diphenyl phosphine oxide compound) in good yield. The structure was analyzed by NMR, IR, HRMS to confirme the structures of the desired product.

The regeneration of thiophene saturated ionic liquid obtained after desulfurization of gasoline were studied. Cyclopentane was used as the extractant to regenerate the ionic liquid( \[C8MIM\] BF4). The dosage of cyclopentane, extraction time and extraction temperature were examined. The optimal operation condition, where V(ionic liquid)∶V(cyclopentane)=1∶2 at 35 ℃ for 15 min were obtained. Under the optimal condition, the backextraction rate of the ionic liquid can reach 8238%. The recovered ionic liquid was further applied to the desulfurization of model oil, and the desulfurization rate can reach 62.37%. 

A series of novel Brnsted acidic organic perrhenates were applied as catalysts for sulfide oxidations using 30% H2O2 as oxidant. The structures and thermal stability data of the catalysts were characterized by FT-IR, NMR and TGA. Meanwhile, the effect of various solvents, the dosage of H2O2 and catalyst, temperature and the reaction time on the catalytic performance was studied in details. The results indicate that the selectivity and yield of sulfoxide can reach up to 95% under the optimal conditions, in which the dosage of catalyst is 0.03 mol, the dosage of H2O2 is 2.4 mmol, 40 ℃ and 90 min.

It is reported herein a novel debenzoylation of diaryl ketones. The effect of the additives, catalysts, and temperature were studied carefully. The results indicate that the yield of this transformation can reach up to 72% under the standard conditions∶ n(ptoluenesulfonic acid)∶n (starting material)=1∶100, n(ethylene glycol)∶n(starting material) =3∶1, toluene, 80 h under reflux. This reaction provides a new method for the debenzoylation of diaryl ketones.
