Nucleophilic attack by substituted hydrazides on C‐2, C‐3 of 2,3,5,6‐tetrachloro‐1,4‐benzoquinone and 2,3‐dichloro‐1,4‐naphthoquinone initiates the formation of benzo[e][1,3,4]oxadiazine and benzo‐ as well as naphthoxadiazepine derivatives. On the other hand, substituted hydrazides attack 1,4‐naphthoquinone‐2,3‐dicarbonitrile to form benzo[f]indazole‐4,9‐dione derivatives. A rationale for the conversions observed is presented. J. Heterocyclic Chem., 2010.
