This element is found coupled to aluminum in (*)Ziegler-Natta catalysts, and it is produced from its tetrachloride via liquid magnesium reduction at 850C in the Krollprocess; that process obtains it from rutile.
It's not silicon, but a halide of this element is used as the Lewis acid in the Mukaiyama aldolcondensation. One compound that contains this non-iron element was synthesized by Birmingham andWilkinson and contains a pair of cyclopentadienyl rings and a pair of halides; that metallocene is found in apair of reagents used for the methylenation of carbonyls. This element is found coupled to aluminum in (*)Ziegler-Natta catalysts, and it is produced from its tetrachloride via liquid magnesium reduction at 850C in the Krollprocess; that process obtains it from rutile. This metal, which is chemically similar to zirconium, has an oxide whichis found in the star-shaped inclusions of star sapphires. For 10 points, name this metal commonly used in lightweightalloys, with atomic number 22 and symbol Ti.
