Area of Science:
- Organic Chemistry
- Synthetic Chemistry
Background:
- Nitrene-transfer reactions are crucial for synthesizing nitrogen-containing organic compounds.
- Advances in transition-metal catalysts and nitrenoid precursors have driven progress.
Purpose of the Study:
- To review the history of nitrene-transfer chemistry focusing on precursor development.
- To comprehensively describe the use of N-heterocycles in nitrene-transfer reactions.
Main Methods:
- Historical overview of nitrene-transfer reaction precursors.
- Detailed examination of N-heterocyclic compounds as nitrene sources.
Main Results:
- Organic azides and iminoiodinanes were early precursors.
