摘要：

Diarylacetylenes and diaryldiacetylenes have been electrooxidized in acetonitrile through the use of a graphite plate anode, thus overcoming a very high passivation. Diarylacetylenes led mainly to 1,2-diaroyl-1,2-diaryl-ethylenes. Anodic oxidation of conjugated diaryldiacetylenes, at the same anode, led to a mixture of acetylenic alpha- and gamma -diketones. This represents the very first synthesis of acetylenic alpha-diketones Ar-CO-CO-C = C-Ar.
