One method of producing this element was replaced because the high vapor pressure of NaCl made it difficult to separate from this element. A low-valent form of this element’s chloride is employed to couple two aldehyde groups to create alkenes in the McMurry reaction. Two cyclopentadienyl rings are coordinated to an atom of this element in a reagent used to convert carbonyls into methylidenes developed by Fred (*) Tebbe (“teb-ee”). This element is not easily purified by reducing its oxides, which include rutile or anatase, and is instead typically produced by adding liquid magnesium to its tetrachloride in the Kroll process. (10[1])This element’s oxide and zinc oxide are the typical compounds in mineral sunscreens. For 10 points, name this corrosion resistant metal with the atomic symbol Ti. ■END■ (10[2])
