Investigation of the reaction of dithiocarbamic acid salts with trimethyl orthoformate and styrene epoxide

摘要

The reaction of dithiocarbamic acid salts with trimethyl orthoformate in the presence of BF3 center dot 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 center dot OEt2 catalyzed reaction of dithiocarbamic acid salts with styrene epoxide is described.
