   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Palladium; catalysis; palladium II catalysis; synthesis; Heck; carboxylic acid; sulfinic acid; sodium sulfinate; nitrile; styrene; ketone; aryl ketone; electrospray ionization mass spectrometry; density functional theory; microwave heating; continuous flow; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

   Abstract : Palladium complexes have the ability to catalyse cross-coupling of two organic moieties through the formation of transient metal-carbon bonds, thus bringing them closer to each other to facilitate the formation of a new bond. Palladium-catalysed coupling reactions are one of the most important carbon-carbon forming reactions available to organic chemists and many of these reactions rely on the reactivity of aryl-palladium complexes.
