Abstract
A novel family of olefin polymerization catalysts comprising three-membered titanacarbocycles is described and illustrated. The titanacarbocycles can be readily synthesized by utilizing di-n-butyltitanium dichloride or di-t-butyltitanium dichloride at −78° C. in alkane, cycloalkane, or aromatic hydrocarbon media. These catalysts exhibit sufficient stability after their preparation that they undergo a remarkable, unprecedented reaction whereby the titanium dichloride moiety is efficiently transferred to a substrate like diphenylacetylene, ethylene, or similar compounds in order to generate the three-membered titanacarbocycles.
