3-Cyanocinnamic acid

3-Cyanocinnamic acid is a reactive, unreactive, and stepwise cycloaddition compound. It can participate in photochemical reactions with other compounds to form photodimers. 3-Cyanocinnamic acid has an optimal reaction temperature of 100°C and a reaction time of 5 minutes. The diradical nature of 3-cyanocinnamic acid makes it sensitive to UV light, and the photochemical reactions are simulated by quantum mechanics calculations. Photodimerisation simulations show that 3-cyanocinnamic acid is capable of forming photodimers with 2-cyanocinnamic acid or 4-cyanocinnamic acid at room temperature.
