Bis(μ-iodo)bis[(−)-sparteine]dicopper: A Versatile Catalyst for Direct O-Arylation and O-Alkylation of Phenols and Aliphatic Alcohols with Haloarenes

Abstract The easy to prepare dimeric bis(μ-iodo)bis[(−)-sparteine]dicopper ([CuI{(−)-spa}]2 complex) is shown to be versatile catalyst for O-arylation and O-alkylation with various aryl halides with phenols and aliphatic alcohols respectively, including less reactive aryl chlorides, such as chlorobenzene under mild conditions.
