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