3-Chlorocyclopent-1-ene → 3-Heptylcyclopentene

Participants

Reaction Steps

The procedure followed is the same as that described in Example 20 substituting 1-bromoheptane (100 g, 0.56 moles) diluted in tetrahydrofuran (100 ml), granular magnesium (25 g) in tetrahydrofuran (100 ml), 0.1 M solution of Li2CuCl4 (1.7 mmoles), and 3-chlorocyclopentene (57 g, 0.56 moles) diluted in tetrahydrofuran (200 ml). The crude product is fractionally distilled under vacuum leaving a clear, colorless oil (49 g, 0.29 moles), BP 41° C./0.35 mm.
