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.
