Tailoring of the pre‐catalyst, the oxidant and the arylsilane enables the first room‐temperature, gold‐catalysed, innate C−H arylation of heteroarenes. Regioselectivity is consistently high and, in some cases, distinct from that reported with palladium catalysis. Tolerance to halides and boronic esters, in both the heteroarene and silane partners, provides orthogonality to Suzuki–Miyaura coupling.
通过对前催化剂,氧化剂和芳基硅烷进行定制,可以实现首次在室温下,金催化的杂芳烃的CH-H芳基化反应。区域选择性一直很高,在某些情况下,与钯催化所报道的区域选择性不同。杂芳烃和硅烷配偶体对卤化物和硼酸酯的耐受性提供了与Suzuki-Miyaura偶联的正交性。
