The reactions of various enaminones with elemental sulfur giving rise to both sulfur-bridged enaminones and chromones have been realized via iodine promotion. All products were furnished by means of double C(sp)-H bond thiolation without using any metal catalyst or sensitive oxidant, providing a simple and efficient protocol for the synthesis of diverse sulfur derivatives of enaminones.
通过碘促进实现了各种烯胺酮与元素硫的反应，生成了硫桥连烯胺酮和色酮。所有产物均通过双C(sp)-H键硫醇化反应制得，无需使用任何金属催化剂或敏感氧化剂，为合成多种烯胺酮的硫衍生物提供了一种简单有效的方法。
