Synthesis, structures, and catalytic reactions of ring-substituted titanium(IV) complexes

A study was performed on the synthesis, structures and catalytic reactions of ring-substituted titanium(IV) complexes. The synthetic methodologies to various classes of titanocenes based on the nature of ring substitution were reviewed. It was shown that the half-sandwich titanocenes and the constrained geometry linked-amido cyclopentadienyl(indenyl) titanium complexes remain the most active area of titanium research.
