The steady state photolysis of thioxanthen-9-one-10,10-dioxide (1) in dichloromethane does not result in any product formation. In hydrogen donor solvents, such as 2-propanol, toluene or cyclohexane, the formation of the corresponding pinacol was readily observed. The phosphorescence spectrum of 1 in EPA, at 77 K, reveals a triplet energy of 66.3 kcal mol−1. Laser flashphotolysis irradiation of a
