Herein, an efficient, metal-free process for the α-C–H thiocyanation of enaminones was developed using PhI(OAc)2 as an oxidant at room temperature in an aqueous medium. Various SCN-containing enaminones and chromones with broad functional groups were synthesized in moderate to good yields in the presence of KSCN. In addition, 3-selenocyanochromone was synthesized using this fast, green, metal-free
在此,在室温下在水性介质中使用PhI(OAc)2作为氧化剂,开发了一种高效,无金属的烯胺酮α-C–H硫氰化方法。在KSCN存在下,以中等到良好的产率合成了各种具有广泛官能团的含SCN的烯胺酮和色酮。此外,使用这种快速,绿色,无金属的方法合成了3-硒代氰基色酮。
