P(NMe2)3-promoted ortho-selective arylation of phenols with diaryliodonium triflates via rhodium catalysis

Rh-catalyzed ortho-selective arylation of free phenol with diaryliodonium triflates to widely existed phenol-containing biaryls have been developed. The use of P(NMe2)3, tBuOLi and CH3CN proved to be critical for the ortho-selectivity of this reaction.
