General description

2-Phenylphenol, also known as o-phenylphenol, is commonly used as a chemical intermediate for the synthesis of pharmaceuticals, dyes, and fragrances.

Application

2-Phenylphenol can be used as a precursor in the synthesis of:
  • Dibenzofurans via palladium-catalyzed, phenol-directed C-H activation/C-O cyclization or copper-catalyzed aerobic C-H activation, followed by cycloetherification.
  • 6H-Dibenzo[b,d]pyran-6-ones via ruthenium-catalyzed carbonylative C-H cyclization.
  • o-Phenylenes, a class of conjugated oligomers via an iterative sequence of Suzuki-Miyaura coupling reactions.
  • o,o,p-Oligophenylenes via palladium-catalyzed C-H arylation.
