摘要

By anodic oxidation of paramethylbenzylsulfonate, ester and nitrite 1 in Et3N, 3HF/CH3CN, regioselective functionalization at benzylic positions is obtained (benzylic fluorides 2 and acetamides 3 are formed). In order to examin the determining factors of the chemioselectivity. It was compared to those obtained in bromination of the same compounds by 1, 3-dibromo 5, 5-dimethylhydantoïn (DBH)/2.2′-azobis (isobutyronitrile)(AIBN) in ...
