Titanocene dichloride (TDC)

 

We are a leading supplier of high purity Titanocene dichloride (TDC). Purity of our TDC is typically 99.8%. 

TDC is used in a wide variety of applications in different industries. 

TDC and its derivatives are used as a catalyst for hydrogenation of rubbers, such as in the manufacture of SEBS. SEBS is widely used to make handles of tools, adhesives, sporting goods, and toys. SEBS is also used in applications where good temperature and ozone resistance is needed, like weather seals where it replaces EPDM. 

Other applications are in organometallic and organic synthesis both as a reagent and as a catalyst. TDC is a useful reagent that effectively behaves as a source of Cp₂Ti²⁺. Examples are:

• The Petasis reagent, Cp₂Ti(CH₃)₂, is prepared from the action of CH₃MgCl or MeLi on Cp₂TiCl₂. Aldehydes and ketones can be selectively methylenated in the presence of less electrophilic carbonyl groups such as esters, amides and carbamates. This reagent is useful for the conversion of esters into vinyl ethers.
• The Tebbe's reagent Cp₂TiCl(CH₂)Al(CH₃)₂, arises by the action of 2 equivalents Al(CH₃)₃ on Cp₂TiCl₂. Tebbe reagent reacts rapidly with ketones and amides, but it only reacts slowly with esters. However, when Tebbe reagent is treated with a Lewis base such as pyridine or THF, a highly reactive Titanocene methylidene is generated. This methylenates a range of carboxylic and carbonic acid derivatives to give the corresponding alkenes at room temperature or below. 

Further, TDC is often used in fine chemical industries as raw material for the manufacture of other catalysts and photoinitiators, e.g. by replacing one or both of the chlorine atoms with other groups. 

We can also convert TDC into your specific target molecule. We provide proprietary technology, scale-up expertise, pilot facilities and commercial scale production for your custom made (metal-)organic specialties.
