Liquid magnesium reduces the common +4 oxidation state of this element in its industrial synthesis, which starts by treating rutile with chlorine gas.
In a bizarre complex, this element binds two cyclopentadiene ligands and a ring containing five consecutive sulfur atoms. All three minerals in Synroc, a mixture used to store nuclear waste, contain this metal. It has the lowest atomic number of the elements that form bent metallocenes rather than sandwich complexes. Diethyl tartrate mixed with this element's isopropoxide is used for stereoselective epoxidation. The principal chloride salt of this element is a yellow liquid that's such a strong Lewis acid, it reacts with air moisture. A heterogeneous (*) catalyst with this transition metal as the active component is used for isotactic propylene polymerization. Liquid magnesium reduces the common +4 oxidation state of this element in its industrial synthesis, which starts by treating rutile with chlorine gas. For 10 points, name this transition metal whose dioxide is found in white paint and which is purified in the Kroll process.
