Overall, the cyanoketene anion provides facile access to complex organic compounds by reaction with various small molecules. These reactions are highly atom economic and produce even industrially meaningful compounds with large incorporation of atoms from sustainable precursors such as carbon dioxide (e.g. 62% of the molecular weight of 8 stems from CO, H2S and HCl). Thus, 2 also represents a valuable building block to structural diversity from abundant feedstock. It is also important to note, that all reactions are fast, being completed within only few minutes of reaction time.
