Versuchsvorschrift

To a three neck 50 ml round bottom, 4-bromostyrene (14.490 g, 0.0786 mol) was added. To the solution, a magnetic stir bar along with dichloromethane (DCM) (10 mL) were added. To the solution, Grubb's catalyst (0.500 mg, 5.8×10−4 mol) along with DCM (25 mL) was added. The solution was allowed to react for 24 hours at room temperature. The precipitate was filtered and placed into a vial for storage.
