Nickel-catalyzed decarbonylative alkynylation of acyl fluorides with terminal silylethynes under copper-free conditions is described. This newly developed method has a wide substrate scope, affording internal silylethynes in moderate to high yields. The formation of 1,3-diynes as homocoupled products and conjugate enones as carbonyl-retentive products were effectively suppressed.
本文描述了在无铜条件下,镍催化的酰氟与末端硅基乙炔的脱羰基炔基化反应。这种新开发的方法具有广泛的底物范围,产率为中到高。成功抑制了1,3-二炔的同偶联产物和共轭烯酮的羰基保留产物的形成。
