  1. 6. Noble Metal Catalysed Reductions and Rearrangements

    Författare :Alban Cadu; Joseph Samec; Anne Fiksdahl; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

    Sammanfattning : The focus of this thesis has been organometallic catalysis applied to compounds containing heteroatoms which are usually poisonous to metal catalysts, by channelling their innate reactivity advantageously. The studies described in this thesis concentrate, in the first part, on iridium catalysed asymmetric hydrogenation (papers I and II) and in the second part, on gold catalysed internal rearrangements (papers III and IV).

  3. 7. Catalytic Amide Reductions under Hydrosilylation Conditions

    Författare :Alexey Volkov; Hans Adolfsson; Andrei K. Yudin; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hydrosilylation; amides; reduction; chemoselectivity; organisk kemi; Organic Chemistry;

    Sammanfattning : This thesis covers the development of catalytic methodologies for the mild and chemoselective reductions of amides. The first part of the thesis describes the use of a Fe(II)/NHC catalyst for the deoxygenation of aromatic tertiary amides to corresponding amines. LÄS MER

  4. 8. Tracking Emissions Reductions and Energy Efficiency in the Steel Industry

    Författare :Johannes Morfeldt; Semida Silveira; Wolfgang Eichhammer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy efficiency; greenhouse gas emissions reductions; indicators; iron and steel industry; systems analysis; energieffektivitet; växthusgasutsläppsminskning; indikatorer; järn- och stålbranschen; systemanalys; Energy Technology; Energiteknik;

    Sammanfattning : The iron and steel industry has become increasingly globalised. Market conditions are also changing and de-carbonisation of production is challenging.The objective of this thesis is to assess how energy efficiency and greenhouse gas emissions reductions can be promoted and effectively monitored in the steel industry.
