New carboalkoxybis(triphenylphosphine)palladium(II) cationic complexes: Synthesis, characterization, reactivity and role in the catalytic hydrocarboalkoxylation of ethene. X-ray structure of trans-[Pd(COOMe)(TsO)(PPh3)2]·2CHCl3

The cationic complexes trans-[Pd(COOR)(H2O)(PPh3)2](TsO) have been synthesised by reacting cis-[Pd(H2O)2(PPh3)2](TsO)2·2H2O with CO in ROH (R = Me and Et), practically under room conditions, or by methathetical exchange of trans-[Pd(COOMe)Cl(PPh3)2] with Ag(TsO) (R = n-Pr, iso-Pr, n-Bu, iso-Bu, sec-Bu). They have been characterised by IR, 1H NMR and 31P NMR spectroscopies. The X-ray investigation of trans-[Pd(COOMe)(TsO)(PPh3)2] reveals that the palladium center is surrounded in a virtually square planar environment realized by two PPh3 trans to each other, the carbon atom of the carbomethoxy ligand and an oxygen atom of the p-toluensulfonate anion, with two crystallization molecules of CHCl3. The Pd–O–S angle, 151.9 (3)°, is very wide, probably due to the interaction of one CHCl3 molecule with the complex inner core. The carbomethoxy derivatives react with R′OH yielding the corresponding R′ carboalkoxy derivative (R′ = Et, n-Pr and iso-Pr); ethene does not insert into the Pd–COOMe bond; decarbomethoxylation occurs when treated with TsOH/H2O in MeOH at 50 °C. All the carboalkoxy are precursors for the catalytic carboalkoxylation of ethene if used in combination of PPh3 and TsOH, better in the presence of some water. Experimental evidences are more in favor of the so-called “hydride” mechanism rather than the “carbomethoxy” mechanism

Imagining the desirable homeland: Nation-related belonging and social media use of young Kazakhstani Russians

Dissertation, Otto-Friedrich-Universität Bamberg, 2021Recent events, such as the Ukrainian crisis, political protests in Belarus, and the Nagorno-Karabakh conflict’s escalation, have clearly demonstrated that the so-called ‘national question’ has remained an acute issue in the post-Soviet space. Being surrounded by Russia’s neo-imperial calls, but also by the dominating titular culture in the country of their current residence, ethnic Russians, and their national belonging arouse the interest of academia. Simultaneously, the tremendous expansion of information and communication technologies (ICTs), as well as the popularity of social media in the ex-Soviet republics, opens new opportunities for the conception of a national image, especially for young people. Hence, the studying of ethnic and civic belonging in the post-Soviet context requires an additional technological viewpoint. While Cyberspace in Kazakhstan remains state-controlled, Russia employs social media to unite its compatriots around the Russian national idea. However, the Internet may also support alternative identity constructions, grassroots movements, and the search for new national belongingness among ethnic minorities. How do young Kazakhstani Russians define their national belonging in the light of their social media usage? Which homeland do they imagine, and which role does Instagram play in this process? To answer these questions, I conducted explorative research, which was based upon a qualitative content analysis of 22 semi-structured interviews with young Kazakhstani Russians and a quantitative content analysis of local Instagram accounts. Interviewing ethnic Russians from big Kazakhstani cities demonstrated that these young people avoid formal national categories and creatively combine their multiple nation-related identities and belongings. Although social media content from Russia is present in their social media feeds, Ka-zakhstani Russians did not express any particular attachment to their historical “homeland.” Instead, they defined themselves as Kazakhstanis and advocated for ethnocultural pluralism and innovation inside and beyond Kazakhstan’s national borders. Their openness towards global cooperation is also reflected in their use of social media. At the same time, a close connection to a local space was widely relevant among Kazakhstani Russians. Posting Instagram stories from their everyday life, communicating with local friends, and consuming local news and event announcements, immersed young Kazakhstani Russians into the local city-related environment. Among the whole geographical and thematic content variety, following one or another urban account was an essential part of Kazakh-stani Russians’ social media use. As the Instagram analysis proved, textual and visual content on city-related accounts has blurred the boundaries between different discursive paradigms of national identity existing in Kazakhstan and presented the country in a positive light. In addition to other usage patterns, this provides an opportunity for these young people to construct a particular image of Kazakhstan, which helps them to find their social identity gratification and maintain positive self-esteem. As a result, their sense of belonging to Kazakhstan grows, allowing them to manage their multiple nation-related memberships while creating new categories beyond any formal definitions

Zwischen Internetkontrolle und Medienkompetenz: Die Jugend Kasachstans, Usbekistans und Kirgistans im digitalen Zeitalter

Das Internet hat in den letzten zehn Jahren auch Zentralasien durchdrungen und ist nun für breite Bevölkerungsschichten zugänglich, wobei insbesondere die Jugend von diesem Angebot Gebrauch macht. Das stellt die autoritären Regierungen Kasachstans und Usbekistans, aber auch die kirgisische Führung, vor neue Herausforderungen. Häufig wird die strenge Kontrolle des Internets mit dem Schutz der Jugend gerechtfertigt. Online-Kriegspropaganda und IS-Rekrutierungskampagnen in den sozialen Medien dienen als Rechtfertigung für eine verstärkte Kontrolle des Netzes. Zugleich wird in politischen Diskussionen häufig Medienkompetenz von jungen Menschen als wichtiger Schutzmechanismus erwähnt. Die zahlreichen diesbezüglichen nationalen Programme erscheinen jedoch aufgrund fehlender technischer Ausstattung, insbesondere in den Schulen im ländlichen Raum kaum realisierbar und man kann nicht ausschließen, dass sie nur schöne Fassade vor tatsächlicher Internetzensur sind
