We report a dramatic improvement in the [IrCl(COD)]2-catalyzed addition reaction of silylacetylenes and imines with 2-4 mol% MgI2 as additive. The reaction is very general, with a wide range of imines providing the amine products in excellent yields under convenient reaction conditions. Importantly, the reaction can be conducted with as low as 0.5 mol% catalyst and proceeds in THF as well as in the absence of solvent.

硅烷基
乙炔和
亚胺的加成反应得到了显着改善。该反应非常通用,具有多种
亚胺,在方便的反应条件下以优异的产率提供胺产物。重要的是,该反应可以使用低至 0.5 mol% 的催化剂进行,并在 THF 中以及在不存在溶剂的情况下进行。
