Hydrochloric Acid → 3-Phenylprop-2-Enal

Participants

Reaction Steps

To a solution of 8 g cinnamonitrile in 100 ml tetrahydrofuran, was added dropwise 50 ml of a 1.5M toluene solution of diisobutylaluminum hydride with ice cooling, and the resulting mixture was stirred at room temperature for two hours. The reaction mixture was slowly poured to 200 ml ice water, hydrochloric acid was then added to dissolve the aluminum hydroxide formed, and the organic layer was collected and dried. Distillation of the dried solution under reduced pressure gave 5.2 g (yield: 63.6%) of cinnamaldehyde.
