Article abstract of DOI:10.1016/S0040-4039(00)61944-5

Photooxygenation of 1,1,3,3-tetramethyl-2-indanone triphenylphosphazine afforded, in addition to the parent indanone and triphenylphosphine oxide, 2,2,5,5-tetramethyl-3,4-benzo-3-penten-5-olide from a carbonyl oxide intermediate and also gave light emission.
