Reaction Steps
45.21 grams of phosphorous trichloride in 50 ml of toluene was added dropwise over 85 minutes to a solution of 123.0 grams of 4,4',6,6'-tetra-tert.-butyl-2,2'-biphenol and 60.6 grams of triethylamine in about 600 ml of toluene and stirred at room temperature overnight (about 20 hours). The reaction product was filtered free of triethylamine hydrochloride, the desired product being isolated by removal of the solvent at reduced pressure to yield a solid m.p. 168°-174°.
