| Use | Overview bis-cyclopentadienyl dimethyl titanium may be used as a methylenating agent for carbonyl compounds. Dicyclopentadienyl dimethyl titanium has many advantages such as easy preparation, simple operation, wide range of reaction and so on. It is applicable to a variety of carbonyl compounds, including aldehydes, ketones, esters, lactones, and readily enolated ketones and more acidic substrates. This reagent is very effective for the methylene reactions of alkyl ketones, aryl ketones and cyclic ketone compounds, although it yields only moderate yields for the reaction of aldehydes. |

DIMETHYLTITANOCENE - Preparation
At -10°C, slowly add Et2O solution of methyl lithium (1.6M,47.3mL,76mmol)(20 minutes) to titanium dichlorocene (33.3mmol) in a suspension of anhydrous toluene (100mL), and stir the mixture at the same temperature for 45 minutes. The reaction mixture was added (via cannula) to a solution of ammonium chloride (1.2g) in water (24ml) cooled to -10°C. The two phases are separated, the organic layer is washed with cold water (3 × 20ml) and salt water (1 × 20ml), dried by sodium sulfate, filtered and concentrated under reduced pressure to 60ml, which contains dicyclopentadienyl dimethyl titanium.
