The polarographic behaviour of benzo[ c ]cinnoline in acetonitrile in the presence of various proton donors (water, phenol, benzoic acid and perchloric acid) is reported. In aprotic medium benzo[ c ]cinnoline is reduced in two one‐electron waves, followed by one two‐electron wave. The most probable final reduction product is 2,2′‐diaminobiphenyl. The addition of proton donors causes a shift and/or appearance of new polarographic waves, which can be related to the reduction of various protonated species.
