S-methyl xanthates, dl-trans-2-dimethylaminocyclohexyl S-methyl xanthalate was rearranged without elimination to the corresponding dithiolcarbonate while the cis isomer suffered over-all elimination. It has been suggested that the dimethylamino group attached to the carbon carrying the xanthate group induces the rearrangement. Other examples studied support this mechanism. 2-Benzamidoethyl S-methyl and
