aminationwithout

Aminationwithout is a neologism used in discussions of organic synthesis to describe a class of processes that install an amino group into an organic molecule without relying on conventional amination reagents such as preformed amines, ammonia sources, or discrete nitrene donors. The term emphasizes approaches that minimize added reagents and avoid prefunctionalization steps, often by exploiting in situ nitrogen generation or alternative energy inputs.

Conceptually, aminationwithout encompasses strategies that enable nitrogen incorporation under conditions that reduce the use of external nitrogen reagents. This can include direct C–H amination, nitrogen incorporation via catalytic activation, or energy-assisted pathways in which nitrogen is introduced through catalytic or photochemical or electrochemical means. Broadly, these ideas seek to expand atom economy and lower reagent overhead by leveraging substrates, solvents, or energy input to furnish C–N bonds.

Status and discussion in the literature are primarily theoretical or speculative at present. Some researchers describe aminationwithout as a potential framework for rethinking direct amination strategies, while others contend that it overlaps with established direct amination and hydroamination concepts. The term has not achieved wide consensus or formal definition, and its boundaries remain a topic of debate.

If realized, the concept could influence sustainable synthesis by promoting one-step nitrogen incorporation with reduced reagent load, with potential implications for pharmaceuticals, polymers, and related fields. As of now, aminationwithout remains a developing idea rather than an established, widely adopted classification.
