Procedures were developed for preparing 3,4,4'- and 2',3,4-triaminodiphenyl ethers by the reaction of 4-acetylaminophenol with, respectively, 4-nitro- or 2-nitrochlorobenzene, followed by nitration of the resulting 4-acetylamino-4'- or -2'-nitrodiphenyl ether, hydrolysis of the product, 4-acetylamino-3,4'- or -2',3-dinitrodiphenyl ether, and reduction of 4-amino-3,4'- or -2'-3-dinitrodiphenyl ether.  相似文献

Special features of the formation of 2-benzoylaminobenzimidazole complexes with copper(II) chloride, sulfate, and acetate were studied. Optimal conditions of obtaining the complexes were found, and chemical compositions, some physicochemical properties, and fungicidal activity of the synthesized compounds were studied.  相似文献

A procedure has been developed for the synthesis of bis(arylcarbonylamino-1H-benzimidazol-5-yl) ethers by reaction of the corresponding substituted benzoyl chloride with sodium cyanamide, followed by treatment of the resulting N-cyanobenzamide with 4-(3,4-diaminophenoxy)benzene-1,2-diamine in acid medium.  相似文献

Derivatives of 1H-benzimidazol-2-amine and halo-, nitro-, methoxy-, and hydroxy-substituted benzoic acids were synthesized, and their fungicide activity against pure Fusarium culmorum and Helminthosporium sativum cultures and pathogenic microflora of wheat and barley seeds in laboratory and field tests was studied. Some compounds were found to exhibit a strong fungicide activity.  相似文献

A procedure was developed for preparation of methyl 5(6)-(4-aminophenoxy)- and 5(6)-(2-aminophenoxy)-2-benzimidazolyl carbamates by reaction of 3,4,4`-triaminodiphenyl or 3,4,2`-triaminodiphenyl ethers respectively with methyl cyanocarbamate in water solution in the presence of 7-10 molar excess of acetic acid. The helminthicidal properties, embryotoxicity, and overall toxicity of compounds obtained were estimated.  相似文献

A procedure has been developed for the synthesis of bis(2-arylcarbonylamino-1H-benzimidazol-5-yl) sulfones by reaction of the corresponding substituted benzoyl chloride with sodium cyanamide and subsequent treatment of the N-cyanobenzamide thus formed with 3,3′,4,4′-tetraaminodiphenyl sulfone in acid medium. The products were tested for fungicidal activity.  相似文献

A procedure was developed for preparing 2-nitro-4-thiocyanoaniline by thiocyanation of 2-nitroaniline with ammonium thiocyanate in acetic acid in the presence of bromine as oxidant.  相似文献

A method for preparing 4-amino-3,4'-dinitrodiphenyl sulfide is developed, based on the reaction of 2-nitro-4-thiocyanatoaniline with 4-nitrochlorobenzene in aqueous-alkaline medium in the presence of a phase-transfer catalyst (PEG 400 or Katamin AB).  相似文献

Methyl 5(6)-(4-aminophenylthio)-2-benzimidazolylcarbamate was reacted with carboxylic acid chlorides to obtain mono- and disubstitution products. The formation of the former involves the aniline nitrogen and of the latter, both the aniline and benzimidazole nitrogens. Biological properties of the products are studied.  相似文献
