Schwartz's Reagent is the common name for bis(cyclopentadienyl)zirconium(IV) chloride hydride). This metallocene is used in organometallic chemistry for the hydrozirconation of alkenes and alkynes.[1][2] The chemical can be purchased or prepared by reduction of zirconocene dichloride with lithium aluminum hydride.[3]
