Description

• General description: 4-Phenylphenol (4-hydroxybiphenyl, 4-HBP), a biaryl compound, is a weakly acidic[1] 4-arylphenol. A study on its crystalline structure has been reported.[2] Its rapid, green synthesis via a Pd(0)-catalyzed Suzuki cross-coupling reaction in water has been reported.[3] The standard molar enthalpy of formation of 4-phenylphenol has been evaluated using combustion calorimetry.[4] The solid-matrix luminescence properties for 4-phenylphenol adsorbed on filter paper has been investigated.[5] A study conducted using the yeast two-hybrid assay suggests that it shows estrogenic activity.[6]
• Application: 4-Phenylphenol may be used in the following studies:As a reactant in the synthesis of new azobenzene sulfonic acid dopants by diazotized coupling reaction with sulphanilic acid diazonium salt.[7]As a starting material in the synthesis of 2,6-poly(4-phenylphenol).[8]As a ligand in the synthesis of aluminum (III) bis(2-methyl-8-quninolinato)-4-phenylphenolate (BAlq).[9]
