One reagent containing this metal has an unusual square methylene bridge to aluminum and can be used to convert a carbonyl group to a methylene group .
One reagent containing this metal has an unusual square methylene bridge to aluminum and can be used to convert a carbonyl group to a methylene group . Another reagent to accomplish the same purpose is the Petasis reagent, which, like Tebbe's reagent, has this metal in its less-common plus 2 oxidation state. This element's tetrachloride is used as a strong Lewis acid for aldol reactions or to make isotactic polypropylene as a Ziegler-Natta catalyst, while the pure metallic form can be produced by the Kroll process. Because this element is biocompatible and osseointegrable, it is used in orthopedic implants and its dioxide is used for the white pigment in sunscreen. FTP, name this transition metal with atomic number 22 which sits above zirconium and is very strong given its light weight.
