    Abstract: The present invention provides a direct oxidation method for saturated hydrocarbon bonds in an organic compound. The method allows an organic compound with a saturated hydrocarbon bond to react with an oxidizing reagent in the presence of cerium complex under visible light irradiation, thus oxidizing the saturated hydrocarbon bond to afford an oxidation product. The present reaction only needs to be carried out at room temperature, while the reaction efficiency remains high. In addition, only visible light is required to provide the energy for activation, rendering the present strategy a milder and greener reaction method. The cerium catalyst used in the method is low in cost, simple and efficient, while the oxidizing reagent used is also stable in nature and low in industrial cost, rendering the catalytic system highly practical. Furthermore, environmental pollution caused by heavy transition metals and peroxides can be avoided in such strategy.

    Abstract: Disclosed are a pyrazole compound or a salt thereof, a preparation method therefor, a herbicidal composition and use thereof. The pyrazole compound or a salt thereof has a structure as shown in formula (I):

    wherein, R represents

    wherein, R', R", and R'" represent hydrogen, C1-C4 alkyl, C1-C4 halogenated alkyl, C1-C4 alkoxy or halogen, R', R", and R'" may be the same or different; R 1 represents C1-C3 alkyl; R 2 represents hydrogen or C1-C4 alkyl; R 3 represents hydrogen or C1-C6 alkyl, optionally substituted phenyl, optionally substituted pyridyl, optionally substituted alkenyl, optionally substituted alkynyl, C1-C6 alkyl carbonyl, C1-C6 alkoxyl carbonyl, C1-C6 alkyl carbonyl methyl, etc. A compound having a pyrazole structure not only has excellent herbicidal effect on barnyard grass, but also is safe to rice in post-emergence application. More surprisingly, it also has good control efficacy on barnyard grass resistant to major herbicides, such as penoxsulam, quinclorac, cyhalofop-butyl, propanil, etc.

    Abstract: The present application relates to a method for photochlorination, and specifically to photochlorination by a photochemical reaction of an aromatic compound with gaseous chlorine so as to prepare a trichloromethyl-substituted benzene, and to a method using bis-(trichloromethyl)-benzene as the trichloromethyl-substituted benzene to prepare by further reaction bis-(chloroformyl)-benzene. Through the control of temperature, illuminance and consumption of gaseous chlorine, the method of this application can greatly improve the purity of trichloromethyl-substituted benzene and further prepare polymer-grade bis-(chloroformyl)-benzene with low cost. The present application also relates to a method for purifying trichloromethyl-substituted benzene, and specifically to a method for purifying trichloromethyl-substituted benzene via molecular distillation. The present application further relates to a photochlorination reactor for use in photochlorination reactions (such as those of the present application).
