Isolation of Single‐Component Trimerization and Polymerization Chromium Catalysts: The Role of the Metal Oxidation State

Abstract

One more trimer: A series of chromium complexes of different oxidation states are employed as catalysts for the polymerization/oligomerization of ethylene. The results suggest a link between chromium oxidation state and catalytic performance, with CrIII leading to oligomerization, CrII to polymerization, and CrI to selective trimerization.
