TCI Practical Example: Olefin Metathesis Using UltraCat

Used Chemicals


To a solution of diethyl diallylmalonate (0.240 mL, 0.99 mmol) in anhydrous toluene (9.8 mL) was added a solution of UltraCat (0.1 mol%, 0.001 mmol, 1.0 mg) in toluene (0.1 mL) in one shot. The mixture was stirred at 40 °C under nitrogen for 2 hours. To the reaction mixture, was added 1,4-bis(3-isocyanopropyl)piperazine (0.5 mol%, 1.0 mg) to deactivate the catalyst. The solvent was removed under reduced pressure to give a crude of 1 (0.187 g, 89%) as a deep orange oil. The residue was passed through silica gel (eluent: hexane) to obtain 1 (0.143 g, 68%) as a light yellow oil.

Experimenter's Comments

Toluene was dried over molecular sieves 4A and was degassed by purging with nitrogen before use.
Preparation of catalyst stock solution: UltraCat (5.0 mg) was dissolved in dry degassed toluene (0.5 mL).
The reaction mixture was analyzed by gas chromatography and the reaction completed within 30 min.
