A new rapid iodination reagent, N1,N3,N5-tris[(2,4,6-trimethylpyridine)iodo(I)]-2,4,6-triphenyl-s-triazine trihexafluorophosphate, was synthesized in a modification of the established synthesis 2,4,6-triiodo-3,5-dimethylphenol presence bis(2,4,6-trimethylpyridine)iodo(I) hexafluorophosphate and used for precise post-modification mono- trisubstituted phenyl compounds. We performed triple iodinat...
The effect of 2-benzylamino-1,3,5-triazines on photosynthetic electron transport (PET) was measured with thylakoids isolated from atrazine-resistant, wild-type Chenopodium album, and spinach to find novel 1,3,5-triazine herbicides bearing a strong PET inhibition. The PET inhibition assay with Chenopodium (wild-type and resistant), yielded a resistance ratio (R/W = I50 (resistant)/I50 (wild-type...
A quantitative structure-activity relationship (QSAR) study was conducted for the prediction of inhibitory activity of 1-phenyl[2H]-tetrahydro-triazine-3-one analogues as inhibitors of 5-Lipoxygenase. The inhibitory activities of the 1-phenyl[2H]-tetrahydro-triazine-3-one analogues modeled as a function of molecular structures using chemometrics methods such as multiple linear regression (MLR) ...
In this investigation a simple synthetic method for the synthesis of trifluoromethyl-1H-benzo[e][1,2,4]triazolo[1,2-a][1,2,4]triazine-1,3(2H)-diones and (trifluoromethyl)benzo [5,6][1,2,4]triazino[1,2-b]phthalazine-8,13-diones has been developed using urazole or phthalazine and aceteimidoyl chloride derivatives at room temperature under ultrasound irradiations. In the comparison to the conventi...
In this work, the reaction of derivatives benzoic acid containing substituents in aromatic ring (1a-o) with 2-chloro-4,6dimethoxy-1,3,5-triazine (4) presence N-methylmorpholine (6) has been synthesized active triazine esters carboxylic acids (3a-o). These compounds obtained potassium butylate (7) vinyl acetate (2) have formed corresponding (5a-o). The electronic effect substitutor affects on ca...
