Abstract
PURPOSE:To obtain the titled compound useful as a raw material for various polymers in good yield, by condensing readily available (2-hydroxyhexafluoro-2- propyl)-4-fluorobenzene as a raw material with fluorobenzene in the presence of HF. CONSTITUTION:(2-Hydroxyhexafluoro-2-propyl)-4-fluorobenzene readily obtained by reacting hexafluoroacetone with fluorobenzene and fluorobenzene [in an amount of 3-4 times based on the (2-hydroxyhexafluoro-2-propyl)-4- fluorobenzene)] are subjected to condensation reaction in the presence of HF [in an amount of 40-60 times based on the (2-hydroxyhexafluoro-2-propyl)-4- fluorobenzene)], preferably at 130-180 deg.C to afford the aimed 2,2-bis(4- fluorophenyl)hexafluoropropane. The above-mentioned compound can be readily produced in a short process by this method.
