The commercial production of this element treats rutile with chlorine gas to produce its tetrachloride.
The isopropoxide of this element can be used along with DET to asymmetrically prepare epoxides from allylic alcohols in a reaction named for Sharpless. A CH2 group and chlorine form a bridge between this element and aluminum in one reagent, and this element's properties are similar to those of zirconium. The commercial production of this element treats rutile with chlorine gas to produce its tetrachloride. That tetrachloride can also be used to polymerize alkenes, where it is referred to as a Ziegler-Natta catalyst. This transition metal is commercially produced in the Kroll process. For 10 points, name this element whose alloys are commonly used in the production of aircraft, which has atomic number 22 and symbol Ti.
