Abstract
Palladium-catalyzed, hydroxy-group-directed C-H arylation of [1,1'-biphenyl]-2-ols with chloroarenes was performed. The reaction showed a broad substrate scope and was successfully applied to pharmaceuticals containing a chloro group. Using 2-heteroarylphenols instead of [1,1'-biphenyl]-2-ols also yielded the desired products. The arylated product was further transformed into a triphenylene derivative.
