The titanium salicylideneimino complex TiCl2{eta(2)-1-[NR=C(H)]-2-O-3,5-Bu-2(t)-C6H2}(2) (R = 2,3,5,6-F4C6H) was synthesized. In the presence of polymethylaluminoxane, the complex efficiently catalyzes polymerization of ethylene and, to a lesser degree, atactic propylene. The resulting polymers are characterized by high melting points, molecular weights, and polydispersity indices, as well as elastomeric (polypropylene) properties.
