The dye (F)*sensitized photooxidation of p ‐diaminotoluene (RH 2 ) was examined by flash‐spectroscopy and the mechanism was elucidated. The first chemical reaction is the generation of two free radicals from the triplet dye and the hydrogen donor. These radicals may react in several ways without oxygen: or additionally with oxygen: The connection of this mechanism with photodynamic action is discussed.
