Previously unknown N-(2-vinyloxyethyl)dithiocarbamate esters were obtained with high yields by the reaction of potassium N-(-2-vinyloxyethyl)dithiocarbamate with equimolar amounts of organic halides in DMSO or ethanol.When heated above 100 deg C without a catalyst or in the presence of trifluoroacetic acid as catalyst at 20-60 deg C, the obtained esters undergo cyclization to 2-methyl-3--1,3-oxazolidines; the reaction is accompanied by the formation of 1,1-diethanes.The reaction of potassium N-(2-vinyloxyethyl)dithiocarbamate with acid chlorides in DMSO leads to 2-vinyloxyethyl isothiocyanate, which is obtained with a better yield by the cleavage of methyl N-(2-vinyloxyethyl)dithiocarbamate in toluene in the presence of catalytic amounts of potassium hydroxide.

A number of unsymmetrical acyl thioacyl sulfides have been prepared and characterized by the reaction of piperidinium or sodium dithiocarboxylates with acyl chlorides or by desulfurization reaction of acyl thioacyl disulfides with triphenylphosphine.They are deep blue oils or light green crystals and very unstable thermally and for moisture.The n --> ?* transitions of the thiocarbonyl group of 1 appear in higher wave length region than those of the corresponding symmetrical bis(thioacyl) sulfides .Some reactions with nucleophiles are discussed.It was found that the symmetricallization reaction of these unsymmetrical acyl thioacyl sulfides occurs in the presence of base such as lithium ethanethiolate to give the symmetrical bis(thioacyl) disulfides in fair yield.
