Coupling of phenols with diphenoquinones
Abstract
Abstract BINARY SELF-CONDENSATION PRODUCTS OF PHENOLS ARE PREPARED BY REACTING THEM WITH DIPHENOQUINONES IN THE LIQUID PHASE. SINCE THE DIPHENOQUINONES THEMSELVES CAN BE PREPARED FROM PHENOLS, THE PHENOLS NEED TO BE THE ONLY STARTING MATERIAL TO PRODUCE THE SELF-CONDENSATION PRODUCTS. BY USING 2,6-DISUBSTITUTED PHENOLS AND THE CORRESPONDING DIPHENOQUINONES PREPARED FROM THE PARTICULAR 2,6-DISUBSTITUTED PHENOL, THE SLEF-CONDENSATION PRODUCT OF THE PHENOL IS A 2,2'',6,6''-P,P''-BIPHENOL AND IS PRODUCED BOTH FROM THE PHENOL AND DIPHENOQUINONE REACTION. SINCE 2,6-DISUBSTITUTED PHENOLS MAY BE MADE BY ALKYLATION OF EITHER PHENOL OR 2-SUBSTITUTED PHENOLS AND THE BIPHENOL PRODUCT MAY BE READILY DEALKYLATED, BIPHENOLS CAN BE MADE WHICH HAVE FROM 0 TO 4 SUBSTITUENTS IN THE 2,2'',6 AND 6'' POSITIONS.
