Wang, Zechao; Yin, Zhiping; Wu, Xiao-Feng published an article in 2018, the title of the article was Copper-catalyzed carbonylative transformations of indoles with hexaketocyclohexane.Quality Control of Methyl 2-methyl-1H-indole-3-carboxylate And the article contains the following content:
With hexaketocyclohexane octahydrate as the carbon monoxide source, a novel procedure for copper-catalyzed direct double carbonylation of indoles was established. Using alcs. as reaction partners, moderate to good yields of the desired double carbonylation products were obtained. Wide functional group tolerance and substrate scope was observed The experimental process involved the reaction of Methyl 2-methyl-1H-indole-3-carboxylate(cas: 65417-22-3).Quality Control of Methyl 2-methyl-1H-indole-3-carboxylate
