  • Applications

    Hydrogenation of rubbers: Titanocene Dichloride and derivatives are used as hydrogenation catalyst for rubbers, like SBS and SEBS, to improve heat stability and resistance to ozone/oxidation [1]. Polymerization: Titanocene Dichloride can be used with polymethylaluminoxane as a catalyst for metallocene type olefin polymerizations [2]. Organic synthesis: 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 [3]; with magnesium for the reduction of organic halides, azo compounds, haloketones, and haloesters [4]; with sodium for the reduction of aliphatic aldehydes, esters, and epoxides [5]; for the reductive decyanation of alkyl nitriles [6]; and the reduction of olefins [7]. Titanocene Dichloride has been used with alkylaluminum compounds for the alkylation of α-olefins [8] and alkynylsilanes [9]. It can be reacted with trimethylaluminum to form Tebbe reagent, which is used to transform a carbonyl into a methylene group [10]. Nouryon 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.
