In the present paper, 50 new derivatives 2-[8-R1-9-R2-10-R3-3-R-2-oxo-2H-[1,2,4]triazino[2,3-c]quinazoline-6-yl)thio]acetic acids have been described. It was shown that alkylation of potassium 8-R1-9-R2-10-R3-3-R-2-oxo-2H-[1,2,4]triazino­[2,3-c]quinazolin... see more

The study of the monitoring and of the dissipation relate 4 herbicides (simazine, prometryn, terbutryn and Terbuthylazyne) of the family of s-triazine compounds. The study of the monitoring has shown that the four molecules are presented, all year round i... see more

A quantitative structure-activity relationship (QSAR) investigation was performed towards 41 hybrids of 4-anilinoquinoline-triazines as potential antimalarial agents. The study was carried out using descendant multiple linear regression analyses (MLR), an... see more

The nucleophilic substitution of the nitro group of 4-alkyl-6-nitro-4,7-dihydro-1,2,4-triazolo[5,1-c][1,2,4]triazine-7-ones on the example of interactionwith morpholine was studied. It is established that under the action of excess cycloalkylimine at room... see more

In the last three decades, the concept of soil humic substances has been questioned in two main directions. Misinterpretations of CP MAS13C NMR spectroscopy led to the conclusion that soil organic matter is mainly aliphatic, questioning the theory of poly... see more

Once pesticides reach the soil, there are several factors that affect their soil behavior. To identify the principal soil and herbicide properties that control their adsorption and leaching, a study of five Chilean agricultural and forest soils was perfor... see more
