What happens when cinnamic acid is heated?
What happens when cinnamic acid is heated?
Pyrolysis of cinnamic acids led to the formation of styrenes. However, as in the case of benzoic acids, heating in quinoline in the presence of Cu or its salts led in general to better results. Heating of ethyl cinnamate in H2O at 220 °C led to the formation of styrene in good yield <1997JOC2505>.
