Abstract
Novel 4-substituted acetophenone anils and methods for preparing 1,3,5-tris(4'-hydroxyphenyl)benzenes from 4-substituted acetophenones such as 4-hydroxyacetophenones or, from substituted 4-hydroxyacetophenone-anils such as 4-hydroxyacetophenone-anil by reacting the 4-substituted acetophenone or corresponding anil with an aniline derivative.
