反应详情

This compound was synthesized from 6-cyanohexyltriphenylphosphonium bromide (9.05 g, 20 mmol) and p-propylbenzaldehyde (2.96 g, 20 mmol) in THF (100 mL) by a Wittig reaction. Kugelrohr distillation afforded the product (3.25 g, 67%) as a colorless liquid (bp 144-148° C./0.05 torr). IR 2290 cm-1 ; 1H-NMR: 0.95 (t, 3 H), 1.55 (m, 8 H), 2.40 (m, 6 H), 5.60 (m, 1 H), 6.40 (d, 1H), 7.10 (s, 4 H).
