  Catalyst systems suitable for tetramerizing ethylene to form 1-octene may include a catalyst including a chromium compound coordinated with a ligand and a co-catalyst including an organoaluminum compound. The ligand may have a chemical structure: (R 1 )(R 2 )A-X—C(R 3 )(R 4 ). A and C may be phosphorus. X may be B(R 5 ), Si(R 5 ) 2 , N(R 5 ), wherein R 5 is an aryl group substituted with a halogen, halogenated alkyl or a silyl group, and wherein B, or N, or Si is bound to A and C. R 1 , R 2 , R 3 , and R 4 may be independently chosen hydrocarbyl groups or heterohydrocarbyl groups.
