    Russian State Policy for the Development of the Far East at the Beginning of the Twentieth Century

    Get PDF
    The proposals of the authorities on the development of the Far East at the beginning of the 20th century are considered. The relevance of studying the past experience in the development of this region is due to the increased attention of the authorities to the introduction of large-scale programs to strengthen the eastern borders of the state. The authors note the increased scientific interest in the study of the history of the Far East development at the beginning of the 20th century. An analysis of government actions in the Amur region during this period allowed the authors to determine their relationship with the foreign policy position of the empire in the Far East. It was determined that the formation of the Committee for the Settlement of the Far East was aimed at consolidating the actions of the central and provincial authorities. The authors note that at the stage of preliminary coordination of the directions of the Committee’s activities, the members of the government did not have a holistic idea of the regional development strategy. A comparative analysis revealed that the proposals of the central and regional authorities did not have any fundamental differences. The pragmatism of the proposals of local governors was noted. The authors come to the conclusion that the creation of the Committee for the Settlement of the Far East and the organization of the Amur expedition were undertaken under the influence of an external threat and aimed at strengthening the military-industrial potential of the region. The authors note that the administrative and economic development of the region was not a priority for the central authorities

    Counteraction to High Treason in Russian Legislation of the Second Half of the 19th — Early 20th Centuries

    Get PDF
    The problem of improving the criminal liability of the subjects of the Russian Empire at the end of the nineteenth century for espionage and spilling state secrets to a foreign state is considered. The relevance of the study is due to the importance of the problem under study for the effective functioning of the Russian state. The study is based on historical sources of a regulatory and legal nature and is interdisciplinary in nature. Particular attention is paid to the study of legal norms, the identification of the type and amount of punishments for the commission of espionage by Russian citizens and spilling the state secrets to a foreign state. It is indicated that in the second half of the 19th century, the intensity of intelligence of foreign secret services in the territory of the Russian Empire increased. It is noted that more and more often foreign powers involved Russian subjects in the process of obtaining Russian secrets. At the same time, the analysis of the sources made it possible to reveal a sufficient limitation of the institution of counteracting espionage and disclosure of state secrets to foreign states in the Russian Empire at the end of the 19th century. It is proved that it was precisely these phenomena at the end of the 19th and the beginning of the 20th centuries that determined the authorities’ desire to progressively improve legal mechanisms that counteract threats and challenges to national security

    Heteropoly acid catalysts in upgrading of biorenewables: Synthesis of para-menthenic fragrance compounds from α-pinene oxide

    Get PDF
    © 2018 Elsevier B.V. The isomerization of α-pinene oxide in the presence of Cs2.5H0.5PW12O40 (CsPW) heteropolysalt as solid acid catalyst is reported. The reactions were performed in various solvents, which allowed to obtain trans-carveol, trans-sobrerol and pinol in 60–80% yield each, which exceed the yields reported so far. The CsPW catalyst could be recovered and reused without loss of its activity and selectivity

    Heteropoly acid catalysts in upgrading of biorenewables: Cycloaddition of aldehydes to monoterpenes in green solvents

    Get PDF
    Acidic Cs salt of tungstophosphoric heteropoly acid, Cs2.5H0.5PW12O40 (CsPW), is excellent solid acid catalyst for liquid-phase cycloaddition reactions of biomass-based and easily available from essential oils monoterpenic compounds, such as limonene, ?-terpineol, ?-pinene, ?-pinene and nerol, with aldehydes, including benzaldehyde, crotonaldehyde as well as biomass-derived cuminaldehyde and trans-cinnamaldehyde. The reactions give oxabicyclo[3.3.1]nonene compounds potentially useful for the fragrance and pharmaceutical industries in good to excellent yields. The process is environmentally benign and can be performed in biomass-derived solvent 2-methyltetrahydrofuran and eco-friendly ?green? organic solvents such as dimethylcarbonate and diethylcarbonate under mild conditions at low catalyst loadings without leaching problems. The solid CsPW catalyst can be easily separated from the reaction media and low-boiling solvents can be removed by distillation. Silica-supported H3PW12O40 also demonstrated good performance in these reactions

    Rhodium catalyzed hydroformylation of kaurane derivatives: A route to new diterpenes with potential bioactivity

    Get PDF
    Kaurenic and grandiflorenic acids are naturally occurring diterpenes whose biological activity has been described. Both acids contain an exocyclic methylenic double bond that allows further functionalization on their structure. In an attempt to expand the number of derivatives of these two natural products, we have undertaken a study on the hydroformylation of the methyl esters of the two acids and the trimethylsilyl ether of kaurenol. These substrates have been hydroformylated by using unmodified Rh catalysts, as well as Rh/PPh3 and Rh/tris-(o-t-butylphenyl)phosphite catalytic systems at 100 °C and 20 bar of CO/H2 (1:1). For the three substrates, the two Rh catalysts modified with P-donor ligands, produced high conversions and chemo- and regioselectivities in the diastereoisomeric pair of linear aldehydes. In all cases, the stereoselectivity observed is strongly dependent of the system used, being the most diastereoselective the least hindered unmodified Rh/CO catalyst. A correlation between the higher diastereoselectivity and the faster [beta]-elimination of the metal-alkyl intermediate observed in the unmodified system is discussed.http://www.sciencedirect.com/science/article/B6TF5-4RVMXFD-3/1/d27e671ad9e0b7fc325dfd0bdf413c7
