Photocatalytic generation of highly reactive alkynes under visible light conditions
(PHYSorg.com Chemistry)

Alkynes are a group of organic compounds that are used to manufacture industrial reagents and polymers. Photolysis of a cyclopropenone with UV-light is a useful method to generate a highly reactive alkyne. However, if the reaction mix contains accompanying compounds that are sensitive to UV light, they will degenerate. Therefore, performing this reaction in the presence of visible light instead will keep such compounds intact. A research team at Kanazawa University has identified catalysts that can facilitate the photolysis of visible-light-stable cyclopropenones under visible-light conditions.
