Akzo Nobel Titanocene Dichloride (TDC) Catalyst

Titanocene Dichloride and derivatives are used as hydrogenation catalyst for rubbers, like SBS and SEBS, to improve heat stability and resistance to ozone/oxidation. Titanocene Dichloride can also be used with polymethylaluminoxane as a catalyst for metallocene type olefin polymerizations. Titanocene Dichloride is a useful reagent for a wide variety of synthetic transformations. It can be used with Grignard reagents for the reduction of aryl and vinyl halides; with magnesium for the reduction of organic halides, azo compounds, haloketones, and haloesters; with sodium for the reduction of aliphatic aldehydes, esters, and epoxides; for the reductive decyanation of alkyl nitriles; and the reduction of olefins. Titanocene Dichloride has been used with alkylaluminum compounds for the alkylation of a-olefins and alkynylsilanes. It can be reacted with trimethylaluminum to form Tebbe reagent, which is used to transform a carbonyl into a methylene group. Akzo Nobel can further convert Titanocene Dichloride into derivatives required by the customer, e.g. by substituting the Cl-atoms by other groups or by replacing the cyclopentadienyl rings with substituted cyclopentadienyl rings.Chemical description: Titanocene dichlorideCAS Number: 1271-19-8Acronym: TDCInformation provided by Akzo Nobel Polymer Chemicals.
