Input (English): In the catalyst for an enantioselective Sharpless epoxidation, this element's isopropoxide forms a complex with DET. This element's ability to osseointegrate has made it ubiquitous in meshes bone replacement therapies such as replacement of skull following brain surgery. It can be extracted from the ilmenite and rutile ores using either the Hunter process or a process where its tetrachloride is dropped on molten magnesium, the commercialized Kroll process. The chloride of this element is included in a complex with aluminum is useful in producing polyolefins in its role in Ziegler-Natta catalysts. For 10 points, name this corrosion-resistant transition metal with atomic number 22 and symbol Ti.
Output (English): Science
