Изучена реакция окислительной циклизации пропентиоамидов и получен ряд новых 2,5-дигидроизотиазолиминиевых солей. Изучено взаимодействие енаминов с ДМАД.In this work, the synthesis of enamines containing residues of primary, secondary, tertiary amines as well as the amide and thioamide group has been done. A comprehensive study of the structure for the synthesized compounds has been made by spectral methods including mass spectra, IR, 1H and 13C NMR, and X-ray analysis. The reaction of oxidative cyclization of propentioamides has been investigated and as a result it was obtained a series of 2,5-dihydroizotiazoliminiun salts. The interaction of enamines with DMAD has been studied.Программа развития УрФУ на 2013 год (п.1.2.2.3

Optimization of Technologies of Section Rolling By the Conditions of Saving Energy Resources using the Expert System

Sort-rolled production is a complex, multi-faceted process characterized by high fuel and electricity costs. Therefore, increasing the efficiency of production and minimizing energy costs is one of the key tasks. The use of expert systems (ES), developed on the basis of modern information technologies of artificial intelligence elements and created on the basis of modern concepts of the mechanics of a deformable body of multiple mathematical models for roll pass design and technologies of rolling, provides the quick solution of this problem. Keywords: expert system, rolling manufacture, hot section rolling, optimum rollingmill practice, costs for fuel and electricity, solution of technological task

Unexpected result for the acylation of arylhydrazonoethanethioamides

The acylation of arylhydrazonoethanethioamides containing primary amino group did not yield acylthioamides as expected. Surprisingly, the cyclic 5-acylimino-2,5-dihydro-1,2,3-thiadiazoles were obtained. The formation of thiadiazoles in this reaction was explained by the higher ability of arylhydrazono-N-acylthioacetamide intermediates to be oxidized comparing to their precursors. The presence of pseudobicyclic aromatic structure in the reaction product was a main factor favoring the formation of 1,2,3-thiadiazole ring. © 2013 Elsevier Ltd. All rights reserved

Synthesis and oxidative cyclization of arylaminopropenthioamides

A new series of arylaminopropenthioamides have been synthesized and it have been shown that their oxidative cyclization leads to the 4-cyano-2-arylisothiazole-5(2H)- iminium salts.Синтезирован ряд ариламинопропентиоамидов, содержащих различные заместители в ароматическом фрагменте и у атома азота тиоамидной группы. Изучена реакция окислительной циклизации аминопропентиоамидов и показано, что продуктами являются 4-циано-2-арилизотиазол-5(2H)-иминиевые соли
