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.
