Shifting From Ziegler-Natta to Philips-Type Catalyst? A Simple and Safe Access to Reduced Titanium Systems for Ethylene Polymerization
Silica-supported titanium(IV) chloride is readily reduced by Mashima and co-workers' reagent (1-methyl-3,6-bis(trimethylsilyl)-1,4-cyclohexadiene) to afford materials active in ethylene polymerisation without need of aluminum alkyl cocatalyst.
