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.
对预催化剂、氧化剂和芳基硅烷进行定制,实现了首例室温下金催化的杂芳烃固有C-H芳基化反应。区域选择性始终很高,在某些情况下,与钯催化报道的情况不同。杂芳烃和硅烷底物对卤化物和硼酸酯均具有耐受性,这为铃木-宫浦偶联反应提供了正交性。
