Darstellung und spektroskopische analyse von oligo{[4-(1,1,3,3-tetramethylbutyl) (bzw. 4-octyl)-2-hydroxy-1,3-phenylen]methylen}en und ihrer Ausgangsverbindungen

4-(1,1,3,3-Tetramethylbutyl)phenol and 4-octylphenol, obtained by Fries rearrangement of the corresponding phenyl carboxylates and subsequent reduction of the carbonyl group, were monobrominated in ortho-position and hydroxymethylated with formaldehyde. Originating from these compounds, six 2,2′-methylenediphenol ( 2a–f ) as well as seven 2,6-bis(2-hydroxybenzyl)phenol derivatives ( 3a–g ) were prepared, which have methyl, 1,1,3,3-tetramethylbutyl, and octyl substituents in various ratios in para-position to the phenolic hydroxy groups. The IR- and ¹H-NMR-spectroscopical analyses confirmed the assumed structures of the synthesized oligo-nuclear phenolic compounds.
