Versuchsvorschrift

It is also known that benzaldehyde and ketene can be reacted in the presence of potassium acetate to give a primary product from which about 22% of cinnamic acid is obtained (J.Am.Chem.Soc. 55, 275 (1933)). Under similar conditions, 30% of cinnamic acid and 70% of styrene were also obtained (Organic Synthesis, Volume I, 215 and 216 C. D. Hurd. C. L. Thomas, (1942)).
