Göttker-Schnetmann, Inigo Stereoselective Copolymerization of Butadiene and Functionalized 1,3-Dienes Leicht, Hannes Leicht, Hannes Mecking, Stefan Mecking, Stefan 2016-07-13T08:41:32Z Göttker-Schnetmann, Inigo eng 2016-06-21 [(Mesitylene)nickel(allyl)<sup>+</sup>][BAr<sup>F</sup><sub>4</sub>–] (Ni-1) catalyzes the 1,4-cis selective copolymerization of isoprene and 1,3-butadiene with 15 (RO)<sub>3</sub>Si-, R<sub>2</sub>N-, RSO<sub>2</sub>-, RSO2NH-, and (RO)<sub>2</sub>B-functionalized 1,3-dienes. Incorporation of the functionalized 1,3-diene occurs very efficiently with high comonomer conversions, as observed, for example, for copolymerizations of 1,3-butadiene with (EtO)<sub>3</sub>Si(CH<sub>2</sub>)<sub>3</sub>C(═CH2)CH═CH<sub>2</sub> (1), PhS(O)<sub>2</sub>(CH<sub>2</sub>)<sub>3</sub>C(═CH<sub>2</sub>)–CH═CH<sub>2</sub> (7), or (pinB)C(═CH<sub>2</sub>)C(CH<sub>3</sub>)═CH<sub>2</sub> (15), while copolymerization rates vary from strongly to slightly decreased when compared to butadiene homopolymerizations. 2016-07-13T08:41:32Z
