A mild Cu or Ag catalyzed oxidative arylthiation of terminal acetylenes is introduced. The process, featuring metal catalyzed C–H bond activation as a key step, leads to the formation of highly substituted mercaptoacetylenes under unprecedented neutral conditions.

An oxidative thiolate scavenging concept in a metal catalyzed reaction is presented and demonstrated on the aerobic Pd and Cu catalyzed cross-coupling of mercaptoacetylenes with arylboronic acids. Synthetic value of the chemistry as the complementary tool to the Sonogashira protocol has been demonstrated on a series of functionalized mercaptoacetylene substrates.
