The Effect of Aromatic Ethers on the Trimerisation of Ethylene using a Chromium Catalyst and Aryloxy Ligands

A catalyst system consisting of a chromium source, a 2,6‐disubstituted phenol and an aromatic ether solvent, on activation with triethylaluminium, is active and selective for the trimerisation of ethylene to form 1‐hexene. The aromatic ether appears to play a role as both solvent and reagent and is...

Zusammenfassung:A catalyst system consisting of a chromium source, a 2,6‐disubstituted phenol and an aromatic ether solvent, on activation with triethylaluminium, is active and selective for the trimerisation of ethylene to form 1‐hexene. The aromatic ether appears to play a role as both solvent and reagent and is pivotal in ensuring both the good activity of the system as well as selectivity to the desired product, 1‐hexene.
