Application of phenylhydrazine base ketone compound as agricultural bactericide

The invention relates to an application of phenylhydrazine base ketone compound as agricultural bactericide, the application of the phenylhydrazine base ketone compound disclosed in a formula (1) for inhibiting or killing fungi which cause crop diseases and the application of the phenylhydrazine base ketone compound as the agricultural bactericide. The phenylhydrazine base ketone compound has the advantage of high activity when being used for inhibiting the fungi which cause crop diseases to grow, is suitable for preventing and curing plant diseases caused by the fungi and can be used for preventing and curing diseases caused by various fungi including rice blast and wheat scab, wherein R1, R2, R3, R4 and R5 are respectively independently selected from hydrogen, halogen, alkyl group, alkoxy, hydroxyl, cyanogroup, trifluoromethyl, sulfamide and nitryl; R6 is selected from hydrogen, halogen, alkyl group, amino, cyanogroup, CH3CH2S-, CH3CO-, CF3CH2CO- or CF3CO- and the like; R7 is alkyl group, hydroxyl, phenyl, halogenated phenyl, alkoxy and trifluoromethyl; X can be nitrogen or carbon, and R5 is not in the presence when X is nitrogen, the formula (1) is shown in the description.

Vinylogous reactivity of enol diazoacetates with donor-acceptor substituted hydrazones. Synthesis of substituted pyrazole derivatives

A regiospecific synthesis of multifunctional pyrazoleshas been developed from a cascade process triggered by Rh(II)-catalyzed dinitrogen extrusion from enol diazoacetates with vinylogous nucleophilic addition followed by Lewis acid catalyzed cyclization a

Pyrolysis of 3-hydroxy-2-arylhydrazonoalkanoic acid derivatives

1,2-Diaza-1,3-butadienes have been obtained from readily available 3-hydroxy-2-arylhydrazonopropanoates under various reaction conditions including pyrolysis, dehydration under Mitsunobu conditions or with acetic anhydride or acetic acid. According to their method of synthesis these 1,2-diaza-1,3- butadienes underwent subsequent reactions to give interesting products, and in the presence of proper dienophiles gave the corresponding cycloaddition products. Also, a new approach to pyrazole-3-carboxylic acid derivatives was discovered during an attempt to dehydrate 3-hydroxy-2-arylhydrazonobutanoic esters.
