HCID 87842-Propenoic acid, 3-phenyl-Yield 40%

Procedure

The reaction of benzaldehyde with ketene at 60° C. with the addition of sodium acetate and subsequent heating of the reaction product to the boiling point is known from Ind. Chem. 41, 768 (1949). Cinnamic acid is thereby obtained in a yield of 40%.

Workup
