Triphenylphosphine → HCID 178520709, compound

Participants

Reaction Steps

A solution of benzyl 4-bromo-but-2-enate (430 mg, 1.68 mmol) and triphenylphosphine (661 mg, 2.52 mmol) in benzene (3 ml) was stirred at room temperature under nitrogen for 20 hours. The resulting white solid was collected through filtration and washed with benzene (3×2 ml), and dried at 100° C. under vacuum to give the title compound (510 mg, 59% yield). 1H NMR (CD3OD): δppm 4.60 (2H, m, slowly disappeared due to deuterium exchange), 5.13 (2H, s), 6.16 (1H, dd, J1=15.3 Hz, J2=1.1 Hz), 6.81 (1H, m), 7.33 (5H, m), 7.78 (12 H, m), 7.90 (3H, m). 13C NMR (CD3OD): δppm 67.6 (t), 68.1 (t), 118.3 (s), 118.8 (s), 119.4 (s), 120.0 (s), 129.3 (d), 129.4 (d), 129.5 (d), 129.6 (d), 129.7 (d), 131.4 (d), 131.5 (d), 131.7 (d), 134.7 (d), 134.85 (d), 134.94 (d), 135.1 (d), 135.2 (d), 135.3 (d), 136.5 (d), 136.6 (d), 136.69 (d), 136.73 (d), 155.7 (s); 165.8 (s).
