    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.

    Description / Table of Contents: The losses in weight and the amounts of formaldehyde split off, which had been determined during the melt condensation of 2.6-dihydroxymethyl-4-methyl-phenol (I) at 130°C were the larger, the higher the analytic content of sodium of the compound was. This content was regulated within a range of 0.01 to 3% by weight of sodium by incorporating the sodium salt of compound I with the highly pure compound I. The amounts of form-aldehyde split off which have been indicated in the literature and which differ considerably from one another are probably due to non controlled sodium contents of compound I since the synthesis of compound I is usually carried out via its sodium salt.
    Notes: Die während der bei 130°C verlaufenden Schmelzkondensation von 2.6-Dihydroxy-methyl-4-methylphenol (I) bestimmten Gewichtsverluste und Mengen von abgespaltenem Formaldehyd waren um so größer, je höher der analytische Natriumgehalt der Verbindung lag; dieser wurde durch Beimischen des Natriumphenolats von I im Bereich von 0,01 bis 3,0 Gew.-% Natrium eingestellt. Die in der Literatur angegebenen, stark voneinander abweichenden Mengen von abgespaltenem Formaldehyd sind wahrscheinlich durch unkontrollierte Natriumgehalte von I bedingt; sie können aus dem Natriumsalz stammen, über das Verbindung I gewöhnlich hergestellt wird.

    Notes: Aus Carbylsulfat und aliphatischen Aminen entstehen bei Verwendung von überschüssigem Amin die Alkylammonium-Salze von N-Alkyl-äthionsäure-amiden. In Gegenwart wäßriger Alkalien führt die Reaktion zu den Alkalisalzen der N-Alkyl-äthionsäureamide.
