実験手順
Potassium carbonate (24.0 g, 173.9 mmol), was added to an ethanolic solution containing salicylaldehyde (19.0 g, 155.7 mmol), and allyl bromide (22.0 g, 181.8 mmol). The resulting suspension was heated to reflux overnight. The precipitated inorganic salt was filtered off. The filtrate was evaporated under reduced pressure to give the desired product, 2-allyloxy-benzaldehyde 23.0 g, yield 91%).
