ChemInform Abstract: Electrooxidation of Diarylacetylenes and Diaryldiacetylenes.
Abstract
Electrochemical oxidation of the diarylacetylenes (I) in acetonitrile (II) at a platinum microanode produces a mixture of the diaroyls (III) and the diaroyldiarylethylenes (IV).
ChemInform Abstract
Electrochemical oxidation of the diarylacetylenes (I) in acetonitrile (II) at a platinum microanode produces a mixture of the diaroyls (III) and the diaroyldiarylethylenes (IV). In addition, the oxazepine (Vb) is obtained as a by-product from dianisylacetylene (Ib) due to reaction with the solvent (II). Under similar conditions, the diaryldiacetylenes (VI) are electrochemically oxidized to yield the diaroylacetylenes (VII) and the acetylenic 1,2-diketones (VIII). (Mechanism).
