  3. 3. Catalytic Functionalization of Allylic Substrates by Palladium Pincer Complexes

    Author : Nicklas Selander; Kálmán Szabó; David Milstein; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Catalysis; Palladium; Pincer Complex; Boron; Multicomponent Reaction; Organic chemistry; Organisk kemi; Organic Chemistry; organisk kemi;

    Abstract : This thesis is based on the development of novel catalytic reactions for the synthesis and application of organometallic reagents. The main focus is directed towards organoboronate derivatives. We developed an efficient procedure for converting allylic alcohols to the corresponding allylboronates using palladium pincer complexes as catalysts. READ MORE
