Cross‐dehydrogenative coupling of various terminal alkynes 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
在OMS-2(Au / OMS-2)上负载金的情况下,使用O 2作为末端氧化剂,可以有效地进行各种末端炔烃和一氢硅烷的交叉脱氢偶联反应,从而以中等至高收率提供相应的炔基硅烷(参见图片) 。观察到的催化确实是非均相的,并且该催化剂可以重复使用至少十次,而不会显着降低其高催化性能。
