| Abstract: | The oxidative coupling reactions of 4.4′-isopropylidene-bis-(2-methyl-6-tert-butylphenol) or 4.4′-isopropylidene-bis-(2-tert-butylphenol) with aqueous alkaline solution of potassium ferricyanide were found to give polymeric products (mol. wt. ca. 4500) which show self-curing reaction by heating. By comparing their spectral data with those of their model compounds, it was found that they contain the cyclohexadienone (o-quinol ether) structure which contributes to the self-curing reaction. |
