    Description / Table of Contents: 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.
    Notes: 4-(1,1,3,3-Tetramethylbutyl)phenol und 4-Octylphenol, erhalten durch Friessche Verschiebung der entsprechenden Phenylester und anschließende Reduktion der Carbonylgruppe, wurden in ortho-Stellung monobromiert und mit Formaldehyd hydroxymethyliert. Aus diesen Verbindungen konnten sechs 2,2′-Methylendiphenole (2a-f) sowie sieben 2,6-Bis(2-hydroxybenzyl)phenole (3a-g) dargestellt werden, die in 4-Stellung zu den phenolischen Hydroxygruppen Methyl-, 1,1,3,3-Tetramethylbutyl- und Octyl-Substituenten in verschiedenen Verhältnissen enthalten. Die IR- und 1H-NMR-spektroskpischen Analysen bestätigten die angegebenen Strukturen der dargestellten phenolischen Mehrkernverbindungen.
