Diarylethenes were obtained from the corresponding ethenyl sulfones by photocatalyzed desulfonylation using UV or blue LEDs. When perylene and i-Pr2NEt were used as a photocatalyst and a sacrificing reagent, respectively, this desulfonylation proceeded smoothly to afford the desired ethenes with the functional groups such as chloro, alkoxy and heteroaromatic rings remaining untouched. The use of a flow photoreactor enabled this desulfonylation to proceed more rapidly to finish in an hour of residence time.

The non-aromatic benzocarbazoles (4) and (10) are isolable stable compounds; (4) are produced by photolysis of the benzotriazoles (3), and on further irradiation undergo aza-di-?-methane rearrangement to give the indenoquinolines (5), whilst as expected (10) is photostable.
