| Popis: |
3-Substituted 5-alkoxy-2-aryl-2H-indazoles were synthesized in low to moderate yields by the TiO 2 -photocatalyzed reaction (λ > 280 nm) of 4-alkoxyazobenzenes in alcohols. The formation of hydroxyalkyl radicals and the presence of an electron-donating alkoxy group in the starting azobenzenes are very important in this reaction. This is an unique method for the synthesis of 3-substituted 5-alkoxy-2-aryl-2H-indazoles from 4-alkoxyazobenzenes. |
