A novel and efficient copper-catalyzed one-pot procedure for the synthesis of 3-N-substituted 1,4,2-benzodithiazine 1,1-dioxide derivatives from 2-halobenzenesulfonamides, amines and CS2 is described. The reaction proceeds through Ullmann-type S-arylation, intramolecular addition of NH2 with C[dbnd]S and dehydrosulfide, which provides a new and useful strategy for construction of cyclic aromatic sulfonamides.

The reaction of dithiocarbamic acid salts with trimethyl orthoformate in the presence of BF3·OEt2 was investigated to give 4-(N,N-dialkyldithiocarbamato)-2-dialkyliminio-1,3-dithietane tetrafluoroborates in good yields. Additionally, a one-pot procedure for the synthesis of 2-iminium-1,3-dithiolanes from the BF3·OEt2 catalyzed reaction of dithiocarbamic acid salts with styrene epoxide is described.
