The one-pot concomitant electrochemical reduction of phenanthrenequinones (1, 2) and arenediazonium salts (3a-f) led to the formation 1,3,4-oxadiazol-2(3H)-ones (4a-f, 5a) dibenzo[c,e]azepines (6a-f) when N-methylformamide was used as solvent. A new pathway, different from those previously described with other aprotic solvents, is proposed. experimental data support a radical mechanism for process followed by an internal rearrangement give products.
