Abstract
In the first section, for the first time, a reaction of dithiocarbamic acid salts with carbonyl compounds has been investigated in the presence of BF3.OEt2. The reaction is temperature dependent meaning that the reaction gives two different products at low and high temperatures. At 15-20 0C, the 2-iminium-1,3-dithietane is the main product.As the reaction temperature goes up, formation of gem-bis(dithiocarbamates) is dominant.In addition, deprotection of gem-bis(dithiocarbamates) was investigated by using of nitric acid as the only deprotecting agent. The structure of a 2-iminium-1,3-dithietane was confirmed by X-ray crystallographic analysis.
