Direct Functionalization of Polystyrenes by Platinum (II)-catalyzed Hydroarylation. A New Methodology for Utilization of Polymers
Direct introduction of an acrylic acid moiety into polystyrenes was first conducted. Reaction of polystyrenes with propiolic acid or its methyl ester in the presence of K2PtCl4 and AgOTf afforded alkenylated polystyrenes with LIP to 35% incorporation of the acrylic acid moiety relative to styrene unit.
