Participants

Reaction Steps

Adamantane bisphenols can be readily made available from the corresponding dibromoderivatives and phenol according to U.S. Pat. No. 3,594,427. Thus, 112 g of 1,3-dimethyl-5,7-dibromoadamantane (III) (0.35 m) (see Example 2a) and 900 g of phenol were heated together at 170° C. for six hours. After termination of the evolution of HBr, the mixture was heated to 220° C. for a further two hour period and the excess phenol was distilled off. The reaction mixture was poured into warm water and the white precipitate was filtered, washed with warm water and dried at 80° C. under vacuum. Yield 117.8 g (97%). The product was recrystallyzed from toluene. MP: 222°-224° C.
