the presence of nickel acetylacetonate afforded N,N"-substituted α,α-dioxoketene aminals. Adducts of acetylacetone with carbodiimides are readily deacetylated with MeONa in MeOH to form acetylketene aminals. Ketene aminals were used for the synthesis of functionalized 1,2,3-triazoles.
在乙酰丙酮镍存在下,乙酰丙酮和乙酰乙酸乙酯与二苯基碳二亚胺和二环己基碳二亚胺的加成反应得到 N,N"-取代的 α,α-二氧烯酮缩醛胺。乙酰丙酮与碳二亚胺的加合物很容易在 MeOH 中用 MeONa 脱乙酰形成乙烯酮缩酮胺醛。胺被用于合成功能化的 1,2,3-三唑。
