Synthesis of Highly Fluorinated 2,2′-Biphenols and 2,2′-Bisanisoles
摘要:
Multiply fluorine-substituted iodo anisoles are efficiently coupled in an Ullmann-type reaction to provide the corresponding bisanisoles. The coupling is selective and even tolerates bromo moieties. Subsequent deprotection of hydroxy groups gives access to highly fluorinated biphenols.
