Construction of C1-symmetric zirconium complexes by the design of new Salan ligands. Coordination chemistry and preliminary polymerisation catalysis studies

Abstract

The first synthesis of achiral and chiral [ONNO′]-type Salan ligands featuring two different phenol arms, and the diastereoselective formation of the corresponding octahedral C₁-symmetric zirconium complexes is described; the activity and isospecificity induction of the [ONNO′]Zr(bn)₂ complexes in 1-hexene polymerisation reflected those of the parent symmetric compounds.
