A palladium-catalyzed decarbonylative alkynylation of amides via C–N bond activation is developed. Compared with the reported Ni/Cu catalyzed reaction, which only proceeded well with silylacetylenes, this transformation was also applicable to both aromatic and aliphatic terminal alkynes, including those bearing functional groups, and thus provided a general and straightforward access to diverse internal
开发了通过C–N键活化的钯催化的酰胺脱羰烷基化反应。与报道的仅在甲硅烷基乙炔上进行得很好的Ni / Cu催化反应相比,这种转变也适用于芳族和脂族末端炔烃,包括带有官能团的炔烃,因此可以方便地获得各种内部炔烃。
