  1. 1. Iron catalyzed C-C coupling reactions - mechanistic investigations

    Författare :Anna Hedström; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iron; homogenous catalysis; cross coupling; C-C bond formation; reaction mechanisms; kinetic investigations; competitive Hammett study; density functional theory;

    Sammanfattning : The mechanism of the iron catalyzed cross coupling of aryl electrophiles with alkyl Grignard reagents was studied. The reaction proceeds via a rate-limiting oxidative addition of the aryl halide to an Fe(I) complex generated in situ. A transmetalation from an aryl Grignard reagent occurs either before or after the oxidative addition. LÄS MER

  3. 2. Tobacco and multiple sclerosis susceptibility

    Nyckelord :;

    Sammanfattning : Multiple sclerosis (MS) is a chronic immune-mediated disease of the central nervous system (CNS) that arises from a combination of a complex genetic predisposition and environmental factors. For northern Europeans, the lifetime risk of MS is 1:400, making it the most common non-traumatic cause of disability in young adults. LÄS MER
