A range of substituted 3,3,4,4-tetracyano-6,8-dithiabicyclo[3.2.1]octanes, viz. compounds 5dg, 5j–m, and 5o–u, have been synthesized from the corresponding allyl dithiocarboxylates by a cation radical cycloaddition reaction, using tetracyanoethylene 2 in acetonitrile. The reaction scope has been studied and the mechanism proposed on the basis of the dithioester's chemical behaviour in respect to oxidizing

The reaction of cinnamyl dithiocarboxylates (1) containing electron-donating substituents at the central carbon atom of the dithioester group (R = p-MeOC6H4, EtO, andp-Tol) with tetracyanoethylene affords 2,2,3,3-tetracyano-4-endo-phenyl-7,8-dithiabicyclo[3.2.1]octanes (2) as well as isomeric 3,3,4,4-tetracyano-2-phenyl-trans-1-dithioacyloxycyclopentanes (3). Dithiabicyclooctanes2 rearrange to the
