Cycloocteno-l,2,3-.seIenadiazole (1) and cyclopentadienyldicurbonylcobalt (2) react in the presence of an excess of elemental sulfur to yield the dithiolene cyclopentudicwyl( 1,2-cyclooctenedith io1ato)cobalt (3). Available evidence indicates that this reaction involves the intermediacy of a cobalt-
