首次报道了炔与一系列α-羰基化合物的无催化剂反式选择性碘烷基化反应。这种前所未有的三组分碘烷基化反应是通过使用(碘乙炔基)三甲基硅烷作为自由基引发剂和碘化物源来实现的。1,2-双官能化提供烯基碘,其是用于构建三取代烯烃衍生物的通用结构单元。
We report the first catalyst-free and trans-selective iodoalkylation reaction of alkynes with a series of α-carbonyl compounds. This unprecedented three-component iodoalkylation reaction is enabled by using (iodoethynyl)trimethylsilane as a radical initiator and iodide source. The 1,2-difunctionalization affords alkenyl iodides, which are versatile building blocks for the construction of tri-substituted alkene derivatives.
