Titanium

In the last 15 years, titanium chemistry has flourished, including examples of titanium in the synthesis of well-defined catalysts as well as structurally characterized molecular species. This article serves to provide an extension to the Comprehensive Coordination Chemistry published in 2003 (CCC, 2003). The complexes have been categorized according to primary ligand type, especially if the ligand in question is involved in or supporting reactivity. While complexes discussed herein are primarily Ti(IV), reduced oxidation states have been annotated where appropriate. Finally, this article includes only structurally characterized complexes of titanium. Papers reporting exclusively the use of titanium (such as TiCl4) for catalysis have been excluded for the purpose of this article, as well as polyoxometalates, which can be found in the respective chapter describing these species. Figures of complexes involved in extensive reactivity, or for which this ligand class is prolific in the support of titanium chemistry, have been included.
