| Abstract: | The addition reactions of acetylacetone and ethyl acetoacetate with diphenylcarbodiimide and dicyclohexylcarbodiimide in the presence of nickel acetylacetonate afforded N,N"-substituted  ,-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. |
