  1. 1. Iron or Copper? - Method Development and Mechanistic Studies on Cross-Coupling Reactions

    Författare :Per-Fredrik Larsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Iron; Copper; Transition metal; Cross-coupling; Reaction mechanism; Kinetic investigation; Hammett study; Sustainable catalysis; Trace-metal; Mass-transfer; Ligand development; Ligand scope;

    Sammanfattning : The area of catalysis has had an immeasurable impact on modern society. This has been acknowledged through several Nobel prizes during the 20th century ranging from Haber (1918) for the synthesis of ammonia to Richard F. Heck, Ei-ichi Negishi, and Akira Suzuki (2010) for palladium-catalyzed cross-coupling reactions. LÄS MER
