Abstract
A catalyst and/or precatalyst for olefin oligomerization comprising one or more coordination complexes having one or more central palladium metal atoms. Each palladium atom is bonded to four ligand donor atoms. Two of the donor atoms are group 16 elements and two of the donor atoms are group 15 elements. Also provided are neutral or cationic coordination complex dimers, so that the two palladium atoms are both bonded to one or two donor atoms from group 16, and each palladium atom is bonded to two donor atoms from group 15. In some instances, each of the two group 16 donor atoms are oxygen and each of the four group 15 donor atoms are nitrogen.
