Reaction of triethylammonium 1, 2-ethanediylbis (carbamodithioate) with 2, 3-dichloro-1, 4- naphthoquinone in DMF furnished N, N'-ethylenebis (2-iminonaphtho [2, 3-d][1, 3] dithiole-4, 9-dione) in 94% yield. Triethylammonium N-arylcarbamodithioates reacted with 2, 3-dichloro- 1, 4-naphthoquinone to give 2-(N-arylimino) naphtho [2, 3-d][1, 3] dithiole-4, 9-diones in good yields. NMR spectroscopic data of the products are discussed.
