Reaction Steps

Three tenths of a part of the di-(3,5-di-tert-butyl-2-hydroxyphenyl) bromomethane produced above is dissolved in 20 parts of ethanol and placed in the reaction vessel just above described. One part of 5 percent aqueous sodium hydroxide solution is added and a slow current of nitrogen is passed through the solution for 20 minutes. The reaction mixture is poured into a vessel containing crushed ice, neutralized with acetic acid and extracted with ether. The ether is evaporated and the residue crystallized twice from aqueous ethanol to yield (3,5-di-tert-butyl-2-oxo-3,5-cyclohexadien-1-ylidene)-(3,5-di-tert-butyl-2-hydroxyphenyl) methane.
