Synthesis of highly fluorinated 2,2'-biphenols and 2,2'-bisanisoles

Org Lett. 2010 Oct 1;12(19):4288-91. doi: 10.1021/ol101698a.

Abstract

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.
