fluoride. Titration with pyridine is important for the selectivity of the reaction. Without titration the corresponding gem-difluoroethyl thioethers are generated. With titration the hydrofluorination reaction can be stopped at an intermediate stage to recover the fluorovinyl thioether, which is a relatively stable functionality to purification and manipulation.

An efficient and operationally straightforward synthesis of 1-methylthio-2-arylethyne derivatives is described based on a desilylativeSonogashira cross-coupling between aryliodides and a silylated surrogate for methylthioacetylene (Me3SiCCSMe). Extension of the process to a selection of other thioether types is also documented.
