Rhodium-Catalyzed Diarylation of Oxalates Using Arylboron Compounds

摘要

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 α-hydroxydiarylacetates. Under similar conditions, the ary-lation of benzoylformate and benzil also proceeds efficiently.
