Patent ID: 8802796

Claim:
A system, comprising: a catalyst resulting from one or more coordination complex dimers dissociating, each of the one or more coordination complex dimers, having two palladium atoms serving as central atoms, wherein (i) each of the palladium atoms are bonded to four ligand donor atoms; (ii) two of the ligand donor atoms are a group 16 element, (a) the palladium atoms both being bonded to a first one of the group 16 elements, and (b) the palladium atoms both being bonded to a second one of the group 16 element; (iii) four of the donor atoms each being a group 15 element, (a) two of the group 15 elements being bonded to a first one of the palladium atoms, and (b) another two of the group 15 elements being bonded to a second one of the palladium atoms; and (iv) monomers taking part in an oligomerization and/or polymerization reaction catalyzed by the catalyst.
