Helical Poly(quinoxaline‐2,3‐diyl)s Bearing Metal‐Binding Sites as Polymer‐Based Chiral Ligands for Asymmetric Catalysis

Living it up: Helical polyquinoxalines with single and multiple metal-binding sites, prepared by living polymerization of o-diisocyanobenzenes, are used in the asymmetric hydrosilylation of styrenes, resulting in comparable enantioselectivities to those obtained by low-molecular-weight catalyst systems (up to 87 % ee, stereochemistry was determined by a chiral initiator) and a turnover number of almost 1000.
