Dye-sensitized photooxygenation of isoniazid has been carried out. The product has been isolated and characterized. The participation of singlet oxygen as the active oxidizing species has also been confirmed. A tentative mechanism for the photooxygenation of isoniazid by singlet oxygen has been proposed.
