Synthesis of Benzoquinone Derivatives Containing Benzotriazole Fragments

摘要

2,3,5,6-Tetrakis(lH-benzotriazol-l-yl)-l,4-benzoquinone was synthesized in 85% yield by reac- tion of 2,3,5,6-tetrachloro-l,4-benzoquinone with 1H-benzotriazole in pyridine at room temperature.Treat- ment of 2,3,5,6-tetrakis(lH-benzotriazol-l-yl)-l,4-benzoquinone with piperidine,omega-amino acids,and aromatic amines gave the corresponding 2,5-diamino-3,6-bis(lH-benzotriazol-l-yl)-l,4-benzoquinones.
