Heterogeneous simplified Maruoka phase-transfer catalyst tethered on poly(styrene-co-acrylamide) microsphere: Structure-activity relationship in enantioselective α-alkylation

The covalent immobilization of valuable Maruoka catalyst onto poly(styrene-co-acrylamide) microsphere was developed for the first time through the copolymerization of styrene-functionalized Maruoka catalyst with styrene and acrylamide by means of suspension polymerization.221
