참여 물질

반응 단계

Iodine (0.335 g, 1.32 mmol), diiodomethane (4.3 mL, 53.0 mmol) and 3-bromostyrene (5 g, 26.4 mmol) were added successively to a suspension of copper (7.5 g, 118.8 mmol) in toluene (50 mL). The mixture was refluxed for 140 h, then filtered and concentrated in vacuo. The residue was distilled under reduced pressure to afford 3-bromo-1-cyclopropylbenzene (0.55 g, 10%) as a colorless oil.
