Suppression of chain transfer via a restricted rotation effect of dibenzosuberyl substituents in polymerization catalysis

The introduction of bulky ortho-steric substituents into alpha-diimine Ni(ii) and Pd(ii) species has been often used as an effective strategy to retard chain transfer in olefin polymerization. In this work, we further demonstrate that the "restricted-rotation" effect originating from diben...
