Cross‐dehydrogenativecoupling of various terminalalkynes and monohydrosilanes efficiently proceeded in the presence of gold supported on OMS‐2 (Au/OMS‐2) using O2 as a terminal oxidant, affording the corresponding alkynylsilanes in moderate to high yields (see picture). The observed catalysis was truly heterogeneous, and the catalyst could be reused at least ten times without a significant loss of
