✦ Synopsis

1-(Alkylthio)difluoropropynes regioselectively add dialkylamines and mercaptans with formation of 1-(alkylthio)-2-dialkylamino(alkylthio)ethenes, which exist only in the form of one (presumably the trans isomer) geometrical isomer. Thermal transformation of 1-(alkylthio

)difluoropropynes occurs at a temperature of under 100ЊC and leads to the formation of 2,4bis(polyfluoroalkyl)-3-(alkylthio)thiophenes.
