A series of novel oligo(halobenzoquinoid) compounds have been obtained from the photoinduced self‐substitution of 2,5‐dibromo‐1,4‐benzoquinone (1a), 2,6‐dibromo‐1,4‐benzoquinone (1b), 2‐chloro‐1,4‐benzoquinone (1c), 2‐bromo‐5‐chloro‐1,4‐benzoquinone (1d), 2,3,5,6‐tetrachloro‐1,4‐benzoquinone (1e) and 1,4‐benzoquinone (1f) in the presence of N, N ‐dimethyl‐ t ‐butylamine (2) in acetonitrile. Dimers, trimers and/or pentamers of these haloquinones were found to be the major products.
