Abstract

The use of 3,4,7,8-tetramethyl-1,10-phenanthroline (Me4Phen) as a ligand improves the Cu-catalyzed cross-coupling reactions of aryl iodides and bromides with primary and secondary aliphatic, benzylic, allylic, and propargylic alcohols. The relatively mild conditions, tolerate a wide array of functional groups on both the electrophilic and nucleophilic coupling partners.
