Breaking the Si‐lence: The direct cross‐coupling of heteroarenes with aryl‐ or alkenylsilanes proceeds efficiently, in the presence of a nickel catalyst, to create a wide range of aryl–and alkenyl–heteroaryl bonds efficiently (see scheme; DMAc=N,N‐dimethylacetamide, bpy=2,2′‐bipyridine). This catalysis represents a new avenue for using organosilanes in the catalytic CH functionalization chemistry
打破沉默:在镍催化剂的存在下,杂芳烃与芳基或烯基硅烷的直接交叉偶联有效地进行,从而有效地形成了广泛的芳基和烯基-杂芳基键(请参见方案; DMAc = N,N-二甲基乙酰胺,bpy = 2,2'-联吡啶)。这种催化作用代表了在催化CH官能化化学中使用有机硅烷的新途径。
