Description

μ-Chloro-μ-methylenebis(cyclopentadienyl)titaniumdimethylaluminum is used in organic synthesis for carbonyl methylenation, A versatile methylenation reagent for the conversion of ketones and aldehydes to olefins, it offers facile reaction with hindered ketones and allows the conversion of esters to vinyl ethers. Tebbe reagent can be used to olefinate aldehydes, to methylenate a chiral polyhydroxyketone with high diasteroselctivity.
