Abstract

A new phenoxy-imine and phenoxy-ketone heteroligated titanium complex was obtained by hydrolysis of one of the two imine moieties of a bis(phenoxy-imine)Ti complex. X-ray diffraction analysis revealed that the complex assumes an octahedral coordination geometry with a cis-phenoxy-O's and cis-Cl's disposition. NMR studies demonstrated that the complex does not undergo disproportionation. In association with methylaluminoxane, the complex behaved as a non-living-type single-site catalyst for ethylene polymerization.
