Sensitized Photorearrangement of 3,3,5-Triaryl-2(3H)-furanones to 3,4,5-Triaryl-2(5H)-furanones. Steady-State and Laser Flash Photolysis Investigations
A novel photorearrangement of 3,3,5-triaryl-2(3H)-furanones 1a-e under acetone or acetophenone sesitization is reported.Sensitized irradiation of 1-a-e in benzene gave a mixture of the photorearranged 2(5H)-furanones 3 and 4, along with the corresponding
