The oxidative coupling polymerization of p alkoxyphenols with Mn(acac)2ethylenediamine catalysts was carried out. The polymerization of pmethoxyphenol with the manganese(II) acetylacetonate [Mn(acac)2]N,N'diethylethylene diamine catalyst in CH2Cl2 at room temperature under an O2 atmosphere afforded a ...

In contrast, attempts on phenol–indoles coupling for the synthesis of benzofuro[3,2-b]indolines have rarely succeeded47. In 2014, Vincent and co-workers reported an oxidative [3 + 2] annulation between phenols and 3-substituted N-acetylindoles for the synthesis of benzofuro[3,2]...
Catalyzed oxidative C-C bond coupling reactions play an important role in the chemical synthesis of complex natural products of medicinal importance. However, the poor functional group tolerance renders them unfit for the synthesis of naturally occurring

These complexes are good catalysts for the oxidative coupling of 2,6-disubstituted phenols. They have been compared to their low molar mass analogue, N-methylimidazole (I). As substrate, 2,6-di-t-butylphenol and 2,6-dimethylphenol were chosen. Kinetic analysis were performed. The results for ...
The EPR and optical spectra of compounds copper(I) chloride—pyridine-O 2, catalysts of the oxidative coupling polymerization reaction of 2,6 dimethyl phenol have been investigated. Analysis of the e.p.r. spectra indicate that, for active complexes in solution, the sigma bonding is appreciable ...
