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.
