Ligand‐Property Control in the Nickel(0)/Butadiene/P‐Ligand Catalytic System: “Electronic” Factors in the Control of Cyclodimer Distribution

Abstract

The cyclodimer distribution in the Ni0/PR3-catalyzed oligomerization of butadiene depends upon “electronic” factors of the ligands. An opposing effect must also be considered, viz. a ligand-induced relative activation or inhibition of the product-forming reaction step. (VCH = vinylcyclohexane, COD = 1,5-cyclooctadiene, Su = substrate = butadiene, m = 0 or 1.)
