Toluene → Potassium biphenyl-2-olate

Participants

Reaction Steps

A mixture of 526.36 grams (3.092 moles) of 2-phenylphenol, a 45% aqueous solution containing 171.79 grams (3.062 moles) of potassium hydroxide and 2000 ml. of toluene was heated to reflux under nitrogen, with stirring, and the water which passed over was collected in a Dean-Stark trap. When all water had been removed by azeotropic distillation, the mixture was cooled and anhydrous potassium 2-phenylphenate was isolated in nearly quantitative yield by filtration and dried under vacuum at 120° C.
