One-Pot Synthesis of Benzotriazoles and Benzotriazole 1-Oxides by Reductive Cyclization of o-Nitrophenylazo Compounds with Benzyl Alcohol
摘要:
Reductive cyclization of 2-[(nitrophenyl)azophenols 1 with benzyl alcohol and sodium hydroxide afforded 2-(2H-benzotriazol-2-yl)phenols 3 and their 1-oxide 2 in good to excellent yields.
