Optically active s-esters of dithiophosphoric acid on the basis of (1S)-endo-(-)-borneol

The ammonium salt of optically active dithiophosphoric acid obtained by the reaction of tetraphosphorus decasulfide with (1S)-endo-(-)-borneol reacts with benzoyl chloride, methyl chloroacetate and epichlorohydrin to form novel dithiophosphate S-esters. © 2013 Wiley Periodicals, Inc

Necessity of estimation methodology improvement concerning the activity of corporate structures with regional features

© International Economic Society. The article is devoted to an urgent problem of regional development - the development of the methodology concerning the effectiveness of corporate structure functioning evaluation, taking into account their regional features. The scientific hypothesis of the research consists in the assumption that the theory and the methodology of economic analysis concerning the activities of corporations must take into account the regional features of development, since they are the most important elements of a regional economic system. Therefore, in the economic analysis of corporation activities, regional factors and development conditions should receive a quantitative and qualitative assessment, which will serve as the basis for managerial decision acceptance. The article examines the role of large corporations in the provision of a region social and economic development; Institutional and organizational-economic conditions of corporation performance success in a region using the example of the Republic of Tatarstan; the principles of economic analysis. The shortcomings of existing methods of analysis concerning the functioning of corporate structures are distinguished from the point of view of the reliability and the completeness of their evaluation. The authors developed and proposed the mechanism of economic activity evaluation among regional corporate structures, which allows to obtain the reliable information while ensuring their economic security. The study was based on the principles of a systematic approach using a wide range of general scientific methods and techniques, namely: comparison methods; coefficients, factor analysis, expert assessments, balance method, horizontal and vertical analysis; the method of situational analysis; the graphical methods of data processing, etc

Bisaryldithiophosphonic acids: Synthesis and their reactions with organyl chlorosilanes, germanes, stannanes, and plumbanes

A method of synthesizing arylbisdithiophosphonic acids was developed by the reaction of 2,4-diaryl 1,3,2,4-dithiadiphosphetane-2,4-disulfides with tri(ethylene glycol) and 1,4-butandiol in anhydrous benzene suspension under mild conditions. The arylbisdithiophosphonic acids thus obtained were transformed into the corresponding diammonium salts. New bis(triorganylgermyl), stannyl and plumbyl, and cyclic diphenylsilyl and diphenylplumbyl derivatives of arylbisdithiophosphonic acids were prepared from the reactions of diammonium salts of the corresponding acids with triorganylchlorogermane, chlorostannane, chloroplumbane, diphenyldichlorosilane, and diphenyl dichloroplumbane

Optically active dithiophosphoric acid, its ammonium salt, and S-esters on the basis of (1 R)-endo-(+)-fenchyl alcohol

© 2014 Taylor and Francis Group, LLC. Optically active dithiophosphoric acid was prepared by the reaction of tetraphosphorus decasulfide with (1R)-endo-(+)-fenchyl alcohol. The ammonium salt of dithiophosphoric acid prepared reacts with methyl chloroacetate and benzoyl chloride to give dithiophosphate S-esters

Economic feasibility of corporate structure creation

© International Economic Society. The development of a modern region economic system is determined not only by natural and climatic conditions and resource opportunities, but also by the entrepreneurship and the efficiency of corporate structure activities, whose man-agement mechanism ensures the realization of the economic potential concerning the used items and production factors. The corporations, as an association of legal entities and individuals provide more than half of the regional budget reve-nues, jobs, enterprise profits, GRP, etc. in order to realize their financial interests under the leadership of a central ad-ministrative apparatus. At the same time, the performance of enterprises included in the composition of corporate struc-tures is not so unambiguous. In this regard, a special interest appears regarding the issue of their entry economic feasi-bility into corporations. This article evaluates the economic feasibility of corporate structure creation based on a com-parative analysis of production and investment activity results concerning Bashneft, Tatneft and TAIF group of enter-prises. The study was based on the principles of a systematic approach using a wide range of general scientific methods and techniques, namely: comparison methods; coefficients, balance method, horizontal and vertical analysis; the method of situational analysis; the graphical methods of data processing, etc

Dithiophosphoric and dithiophosphonic acids and their derivatives on the basis of thymol: Synthesis and antimicrobial activity

Biologically active dithiophosphoric and dithiophosphonic acids, their ammonium salts as well as S-silyl and S-plumbyl derivatives were prepared by the reaction of thymol with tetraphosphorus decasulfide and 2,4-diaryl 1,3,2,4-dithiadiphosphetane-2,4-disulfides. © 2013 Copyright Taylor and Francis Group, LLC

Assessment of urban air pollution caused by motor vehicle complex and industrial facilities

This paper deals with the collected, processed and systematized information about the existing sources of air pollution caused by the facilities of Naberezhnye Chelny, their physical properties, qualitative and quantitative composition, as well as full-scale survey of the composition and intensity of traffic environment. Based on these data the summary calculation of emissions from factories and motor vehicles was performed. The content of pollutants was instrumentally measured in ambient air and the graphs of correlation between calculated and measured concentrations were constructed

Development of a method of analysis of the financial condition of the enterprise taking into account the life cycle and features of its functioning

© 2019, Dorma Journals. All rights reserved. A disadvantage of the traditional methodology for analyzing the financial condition of an enterprise is the lack of theoretical and methodological developments adapted to Russian business conditions that allow differentiating the subject of research depending on industry and regional affiliation, as well as the stage of the life cycle and the scale of functioning of corporate structures. Ignoring the regional and sectoral affiliation, the stage of the life cycle and the scale of the enterprise’s activity in a comparative analysis of the actual and normative values of the financial condition indicators does not make it possible to formulate the correct conclusion about the degree of financial stability of the enterprise. It is too early to draw any conclusions regarding the financial condition of the enterprise at an early stage of its life cycle, which is explained by the work of the enterprise not at full capacity. The company, at the stage of its birth, is still unstable, since it has a significant share of borrowed capital, risk indicators are high, and solvency ratios do not reach the recommended values, which contradicts the concept of “sustainability”. At the same time, if the idea of implementing the business of this enterprise is successful, then at the next stages the investment will pay off and bring the expected profit. An important factor in the analysis of the financial condition of the enterprise is also its industry and scale. Neglect of these factors leads to a distortion of the assessment of the level of the financial condition of the enterprise
