Phospha-1,2-dioxetanes: possible chemiluminescent intermediates of photooxygenation of benzophenone and fluorenone triphenylphosphazines

Article abstract of DOI:10.1016/S0040-4039(00)92593-0

Photosensitized oxygenation of enzophenone and fluorenone triphenylphosphazine (1a-b) at -78 °C gave the corresponding ketone (5a-b) and triphenylphosphine oxide (6) and also gave light emission when warmed up to room temperature.
