2-Fluorobenzotrifluoride was used in the synthesis of 2,2′-bis(trifluoromethylphenoxy)biphenyl via nucleophilic aromatic substitution reaction with 2,2′-biphenol. | [Synthesis]
General procedure: In a FEP or PFA reactor equipped with a PTFE-lined magnetic stirring bar and connected to a gas scrubber bottle, substituted benzene (0.95-1.10 mmol), 1,1,1,3,3-pentafluorobutane (2 ml per ml C6H5R), and BF3-Et2O (1.3-1.5 mmol per mmol C6H5R) were added. The mixture was stirred at 0-5 °C (ice bath) for 10-15 min, followed by batchwise addition of XeF2 (1.2-1.3 mmol per mmol C6H5R). After each addition, the mixture was stirred at 22-25 °C for 3-5 min and cooled again. After the addition was completed, the dark solution was continued to be stirred at 22-25 °C for 15-30 min. Subsequently, 10% aqueous KHCO3 solution was added and the upper organic layer was separated and filtered through a short column equipped with silica gel (40-60 μm) and finally dried with magnesium sulfate. The solution was analyzed by 19F NMR and GC/MS. The major products are listed in the table and other products are as follows (GC/MS data). | [References]
