실험 절차

One gram (5.5 millimoles) of 1-bromo-2-butoxyethane was combined with 5.5 grams (30 millimoles) of 4,4'-dihydroxybiphenyl in 75 mls. of acetonitrile. To the reaction mixture were added 8.3 grams (60 millimoles) of finely ground potassium carbonate. Stirring was begun and the reaction mixture was brought to reflux and maintained for 48 hours. The reaction product was filtered, washed with acetonitrile and evaporated for removal of solvent. The product was passed through a silica gel chromatographic column using dichloromethane eluent, for recovery of 0.25 gram (20% yield) of a biphenol ether compound having the following formula confirmed by TLC, IR and mass spectral analyses: ##STR26##
