Notes:
Indazoles and anthranils on irradiation with a mercury high-pressure lamp in acidic solution (H2SO4/H2O or H2SO4/CH3OH) yield 2-amino-5-hydroxy(or methoxy)-benzaldehydes (acetophenones, respectively) as major products and 2-amino-3-hydroxy (or methoxy)-benzaldehydes (acetophenones, respectively) as minor products. Photolysis of benzisoxazoles in conc. sulfuric acid results in the formation of 2,5-and 2, 3-dihydroxybenzaldehydes (acetophenones, respectively). 5-Methylindazoles form on irradiation in diluted sulfuric acid 2-amino-5-methyl-benzaldehydes.
