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.

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.
Enhancement of seed yield of soybeans by a substituted benzoyl urea
A method is disclosed for increasing yield in soybeams by applying, in the absence of insect pressure on the crop, an amount effective for increasing seed pod formation of an active amount of a substituted benzoyl urea represented by structural formula (I).

Process for the preparation of benzoyl ureas
Benzoyl ureas of the formula STR1 are prepared by starting from benzoyl derivatives of the formula which are converted via the corresponding azides into the isocyanates, which are in turn reacted with corresponding benzamides.

Method of reducing infestation of citrus rust mites on citrus trees
A method of reducing the population of the citrus rust mite on citrus trees by treating the trees with such substituted benzoyl phenyl ureas as N-(2,6-difluorobenzoyl)-N'-(3-fluoro-4-chloro-phenyl) urea and N-(2,6-difluorobenzoyl)-N'-(4-chloro-phenyl) urea.
