The electrochemical oxidation of 2,5-diphenyl-3-acetylpyrrole (I) is described.The cyclic derivative 1,6a-dihydro-2,5,6a-triphenyl-3,4-diacetylbenzopyrroloindole (II) was obtained in very good yield.However, when water was present in the reaction medium, a different derivative, 4-acetyl-2-hydroxy-2,5-diphenyl-3-(4'-acetyl-2',5'-diphenyl-3'-yl)-2-H-pyrrole (III), was obtained as the main product. 2,2',5,5'-Tetraphenyl-4,4'-diacetyl-3,3'-dipyrryl (IV), a potentially useful intermediate for the synthesis of condensed pyrroles, was synthesized by zinc reduction of III.
