2-(1-Methylindol-3-yl)-3-phenyldihydro-1,4-dioxin 2,3-epidioxide, a dioxetan resulting in efficient ultraviolet chemiluminescence
Abstract
The title dioxetan (5), prepared by photoxygenation of the dihydrodioxin (3) gives u.v. light (λmax 320 nm) on decomposition, the efficiency of excited singlet molecule formation being at least 50%.
