Abstract

A series of air/water-tolerant chiral Pd alkyl complexes (R₂-(S,S)-BOZ)PdR′ (1-3, R = CH(CH₃)₂, Ph; R′ = Me, Ph) were synthesized and structurally characterized. In the presence of an excess of activator, such as [Ph₃C][B(C₆F₅)₄], [PhMe₂NH][B(C₆F₅)₄], or B(C₆F₅)₃, the air/water-tolerant chiral Pd(ii) alkyl complexes 1-3 could promote the norbornene polymerization in air and water using unpretreated technical grade solvent and monomer with extremely high activity up to 1.7 × 10⁹ g PNB per mol_Pd per h.
