    Abstract: The invention relates to a bismuth-containing catalyst as such, which is defined by the general formula (I) detailed in the subsequent text. The bismuth-containing catalyst comprises at least one residue R1, which comprises a carboxyl fragment according to the general formula (II), wherein the first carbon atom (α-carbon), which is bonded directly to the carbon atom of the carboxyl group, is part of an aromatic fragment. The present invention further relates to a method for preparing a bismuth-containing catalyst of this kind and also to the use of such a bismuth-containing catalyst for preparing compounds comprising a urethane group.

    Abstract: Catalyst systems suitable for tetramerizing ethylene to form 1-octene may include a catalyst having a structure according to Formula (VI) or Formula (VII). In Formulas (VI) and (VII), X is a halogen, a (C2-C30) carboxylate, acetylacetonate, or a (C1-C30) hydrocarbyl; L1 is a neutral coordinating ligand; n is an integer from 0 to 6; Y is a (C6-C20)fluorine-substituted aryl, a (C6-C20)fluorine-substituted aryloxy, or a (C1-C20)fluorine-substituted alkoxy; and L∩L is a bidentate chelating ligand. The catalyst system may also include an aluminum containing agent which includes a reaction product of an organoaluminum compound and an antifouling compound. The antifouling compound may include one or more chlorinated hydrocarbons, chloro-aluminum alkyls, or combinations of these.
