  2. 1. Transition metal-catalysed isomerisation of allylic alcohols : Applications to C−C, C−F and C−Cl bond formation

    Author : Nanna Ahlsten; Belén Martín-Matute; M. J. Jonathan Williams; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transiton metal-catalysis; allylic alcohols; isomerisation; halogenation; organisk kemi; Organic Chemistry;

    Abstract : The focus of this thesis has been to develop selective and atom-economical methods for carbon-carbon and carbon-heteroatom bond formation, and to some extent improve on existing findings in this area. More specifically, methods for the catalytic generation of enolates from allylic alcohols and their in situ functionalisation with electrophilic reagents are described. READ MORE

  7. 5. Hype or Hope? : The Democratic Values of Swedish Hyperlocals in the Media Ecology

    Author : Lottie Jangdal; Lars Nord; Elisabeth Stúr; Carl-Gustav Lindén; Mittuniversitetet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : Local media are often credited with an integral role in the local community, tying individuals together in a shared identity or community, where local news can foster community engagement and audience participation, providing more agency in democratic processes (Lie, 2018b; Nelson & Kim, 2020; Wenzel, 2019).This doctoral compilation thesis focuses on so-called “hyperlocal media”, which are typically citizen-led, participatory and largely independent (Turner, 2015), with content concentrated to a small geographically defined community (Radcliffe, 2012).
