titanium trichloride

In a so-called reductive arylation with 3-buten-2-one, titanium trichloride reduces the newly formed double bond.

Titanium trichloride can reduce nitrate to ammonium ion thereby allowing for the sequential analysis of nitrate and ammonia.

Typically these conversions are catalyzed heterogeneously by titanium trichloride which are activated by aluminium alkyls.

McMurry and Fleming coupled retinal to give carotene using a mixture of titanium trichloride and lithium aluminium hydride.

Slow deterioration occurs in air-exposed titanium trichloride, often resulting in erratic results, e.g. in reductive coupling reactions.

Other compounds include titanium tetrachloride (TiCl), a component of smoke screens and catalysts; and titanium trichloride (TiCl), which is used as a catalyst in the production of polypropylene.

A related reaction is the McMurry reaction, which uses titanium trichloride or titanium tetrachloride in conjunction with a reducing agent for the formation of the metal-diol complex, and which takes place with an additional deoxygenation reaction step in order to provide an alkene product.
