First Synthesis of 1,1,4,4-Tetrakis(2-hydroxyphenyl)-butane Type Compounds from Condensation of p-Substituted Phenol Derivatives with 2,5-Dimethoxytetrahydrofuran in Trifluoroacetic Acid

Abstract

Condensation reactions of 2,5-dimethoxytetrahydrofuran with p-substituted phenols and 2-naphthol in trifluoroacetic acid produce 1,1,4,4-tetrakis(2-hydroxyphenyl)butane type compounds and 1,2-bis(1,3-dibenzo[ a,j]xanthyl)ethane in good yields.
