Notes:
In order to make a decision between the quinone acetal equilibration/quinone acetal rearrangement and the so far discussed SET mechanism for the oxidative coupling of 2,6-xylenol to poly(oxy-2,6-dimethyl-1,4-phenylene) the polymerization was carried out in the presence of 5-(2,6-dimethylphenoxy)-2-methoxy-1,3-xylene (1) (the methylated dimer) or α-methyl-ω-phenoxypoly(oxy-1,4-phenylene) [O-methylated poly(phenylene ether)] (2). GC and GPC studies indicated that neither 1 nor 2 are incorporated into the polymer. These observations exclude the SET-mechanism according to Scheme 4.
