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 (15[2])reaction. (15[1])Two cyclopentadienyl rings are (-5[1])coordinated to an atom of this element (-5[1])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 (10[1])by adding liquid magnesium to its tetrachloride in the Kroll process. (10[1])This element’s oxide (10[1])and zinc oxide are the typical compounds in mineral sunscreens. For 10 points, (10[1])name this corrosion resistant metal with the atomic symbol Ti. ■END■ (10[4])
