Abstract (en)
[origin: WO0132724A1] A catalyst composition that is formed by combining (a)(i) an iron compound and a halogen-containing compound or (ii) a halogen-containing iron compound, (b) a hydrogen phosphite, and (c) an organoaluminum compound. This catalyst composition is particularly useful for preparing oligomers of conjugated dienes.
