- Synthesis process and application of diflubenzuron
-
The invention relates to the field of diflubenzuron preparation, in particular to a synthesis process and application of diflubenzuron. The diflubenzuron synthesis process comprises the steps: mixing an aromatic hydrocarbon solvent and 2,6-difluorobenzamide, increasing the temperature to 130-145 DEG C, carrying out reflux dehydration, cooling, adding p-chlorphenyl isocyanate in a dropwise manner, after dropwise adding is finished, increasing the temperature to 130-145 DEG C, carrying out a reaction, and performing post-treatment to obtain the product. The synthesis process of the diflubenzuron is simple, the yield of the prepared diflubenzuron is greater than 92 wt%, and the purity of the prepared diflubenzuron is greater than 97 wt%.

- Hydrogen bond directed aerobic oxidation of amines via photoredox catalysis
-
An application of H-bonding interactions for directing the α-C-H oxidation of amines to amides and amino-ketones catalyzed by an organic photocatalyst is reported. The high efficiency of this method is demonstrated by the aerobic oxidation of pyrrolidines, diarylamines and benzylamines bearing urea groups with high yields and a wide substrate scope.

- New synthesis of aryl and heteroaryl N-acylureas via microwave-assisted palladium-catalysed carbonylation
-
A new, practical synthesis of aryl and heteroaryl N-acylureas has been developed via palladium-catalysed carbonylation of aryl or heteroaryl halides in the presence of urea nucleophiles. A range of reactions illustrating the wide scope of this reaction was carried out under microwave irradiation, using either carbon monoxide gas in a vessel equipped with a gas inlet adapter, or molybdenum hexacarbonyl as the carbon monoxide source in standard microwave vials. The reactions proceeded in good to excellent yields. To illustrate the usefulness of this method a one-step synthesis of the important insecticide diflubenzuron is reported.

- Synthesis and insecticidal evaluation of propesticides of benzoylphenylureas
-
Two series of benzoylphenylurea derivatives were synthesized as candidate propesticides by a nucleophilic addition reaction between 2,6-difluronbenzoyl isocyanate and N-substitutedaniline. The new compounds were identified by 1H NMR spectroscopy, electron ionization-mass spectrometry, and elemental analyses. The bioactivities of the new compounds were evaluated. All of the propesticides reported here were soluble in most organic solvents, and their hydrophobicities were improved obviously. The result of the bioactivities of the new compounds against Oriental armyworm showed that some of the new compounds are good as compared to diflubenzuron and penfluron.
