Rhodium-catalyzed diarylation of oxalates using arylboron compounds.
Dialkyl oxalates undergo selective diarylation on one of their carbonyl carbons upon treatment with arylboron reagents in the presence of a rhodium catalyst to give the corresponding alpha-hydroxydiarylacetates. Under similar conditions, the arylation of benzoylformate and benzil also proceeds efficiently.
