Photoaddition Reactions of Alkynes to Quinonoid Compounds
Sung Sik Kim*, Ae Rhan Kim, In Ho Cho, Sang Chul Shim
UV irradiation of anthraquinone and diphenylacetylene in benzene gave 1:1 photoadduct (7) and cyclization product (8). The photoreaction of anthrone and diphenylacetylene in dichloromethane afforded the photooxidation products (7, 8, and 9) in air. The photoproduct (7) underwent the cyclization reaction during the purification by the column chromatography (silica gel). When irradiated with 350 nm UV light, the product (11) of benzil reacted with diphenylacetylene to give a photoadduct(12).
