Reaction of 1,8-Dehydronaphthalene with Carbon Disulphide

The reaction of carbon disulphide with 1,8-dehydronaphthalene, generated by oxidation of 1-amino-1H-naphthotriazine (7), gave naphthothiet (10) (6-8percent), naphtho-1,3-dithiin-2-thione (11) (3-5percent), naphthothiophen-2-thione (12) (4-5percent), and naphthothiophen-2-one (13) (4-5percent).The results can be explained by radical addition of 1,8-dehydronaphthalene to the sulphur atom of carbon disulphide forming a new 1,5-diradical intermediate (8), from which the final products are derived.
