  2. 1. Palladium-Catalysed Carbon–Carbon Coupling Reactions : Focusing on Microwave Heating, Low Catalyst Concentrations, Aqueous Conditions, Regioselectivity and Medicinal Chemistry Applications

    Author : Riina K Arvela; Mats Larhed; Anders Hallberg; Michael G Organ; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Suzuki coupling; Heck reaction; palladium; microwave heating; water; vinyl ethregioselective; HIV-1 integrase inhibitor; Pharmaceutical chemistry; Farmaceutisk kemi; farmaceutisk biokemi; Pharmaceutical Biochemistry;

    Abstract : It is widely accepted that palladium is one of the most useful catalysts in organic chemistry, and many palladium(0)-catalysed carbon–carbon bond-forming reactions have been developed over the years. In addition, the ever-growing need for more environmentally benign processes in the chemical industry has driven scientists to look for greener options while developing new methodologies for organic synthesis.
