Cross‐coupling reactions of unactivated aryl sulfides with alkynylmagnesium chloride have been invented to afford 1‐aryl‐1‐alkynes with the aid of a palladium/N‐heterocyclic carbene complex. This reaction has by far the widest scope of all transformations utilizing aryl sulfides and alkynes, while known cross‐coupling alkynylations of aryl‐sulfur electrophiles require activated azaaryl sulfides, thiolactams,...
