== trans-Cycloheptene == Under normal conditions, the cycloheptene double bond forms the cis isomer. However, the unstable trans isomer is an accessible reactive intermediate. Methyl benzoate catalyzes singlet photosensitization; irradiating cis-cycloheptene and it with ultraviolet light at −35 °C produces a detectible trans-cycloheptene population.
