, p. 1261 - 1262 (1983)

2-Ethoxy-1,3-oxathiolane was deprotonated at the 4-position, followed by the cycloelimination of the resultant anion, leading to ethyl formate and the ethenethiolate anion.The anion was trapped by several chloromethyl alkyl ethers and sulfides to afford alkoxy(vinylthio)methanes and alkylthio(vinylthio)methanes, respectively.
