Abstract A new and useful synthetic route to 1,3-dithiolium salts involving neighboring group participation of dithiocarbamate group as a key step is described. 4-Bromo-2-dialkylamino-1,3-dithiolan-2-ylium bromide was obtained in high yield by the addition of equimolar bromine to S-vinyl-N,N-dialkyldithiocarbamate, and then, pyrolysis of

A NEW APPROACH TO PREPARATION OF 1,3-DITHIOLIUM SALTS
Synthetic Communications, 2001The synthesis of 4-(3′,5′-diiodo-2′-hydroxy-phenyl)- 2-(N,N-dialkylamino)-1,3-dithiolium perchlorates has been performed by cyclization of the corresponding N,N-dialkylaminocarbodithioates in presence of the “superacid” mixture P2O5–CH3SO3H.

Chemistry of Heterocyclic Compounds, 1984
A method for the preparation of 4-ethoxycarbonylmethyl-, 4-N-phenylcarbamoylmethyl-, and 4-carboxymethyl-1,3-dithiole-2-thiones and the corresponding 1,3-dithiolium salts from γ-bromoacetoacetic ester, γ-bromoacetoacetanilide, and sodium tertbutyltrithiocarbonate was developed. The compounds were characterized by their IR and PMR spectra.
