| Outline of Final Research Achievements |
Among the heteroatom-substituted alkynes and allenes, those with nitrogen substitutions have become an important building block in modern organic synthesis. In contrast to the well-defined ynamides and allenamides, to date, there are little examples of imide derivatives. We have recently reported the Cu-catalyzed coupling of alkynyl(triaryl)bismuthonium salts with imides to furnish the first reliable synthetic method of ynimides. Now we found a first convenient approach for the synthesis of internal allenimides via silver-mediated isomerization of ynimides. Allenimides could be used as synthetic building units in the synthesis of heterocyclic compounds.
