Described is a process for preparing an equilibrium mixture containing 1-(2,6,6-trimethyl-1,3-cyclohexadien-1-yl)-1,3-butanedione and its enol, which equilibrium mixture contains compounds having the structures: STR1 which process involves first reacting a methyl magnesium halide with 1-acetyl-2,6,6-trimethyl-1,3-cyclohexadiene to form a first organometallic compound; reacting the first organometallic compound with an acetyl halide to form a second organometallic compound, a novel intermediate; and then reacting said second organometallic compound with a hydrolyzing agent such as aqueous acid to form said equilibrium mixture.
