Photocatalytic Intramolecular C-H Amination Using N-Oxyureas as Nitrene Precursors

Nitrenes are remarkable high-energy chemical species that enable direct C-N bond formation, typically via controlled reactions of metal-stabilized nitrenes. Here, in contrast, the combined use of photocatalysis with careful engineering of the precursor enabled C-H amination forming imidazolidinones and related nitrogen heterocycles from readily accessible hydroxylamine precursors. Preliminary mechanistic results are consistent with the formation of free carbamoyl triplet nitrenes as reactive intermediates.

Reactions of 2-unsubstituted 1H-imidazole 3-oxides with 2,2-bis(trifluoromethyl)ethene-1,1-dicarbonitrile: A stepwise 1,3-dipolar cycloaddition

The reaction of 1,4,5-trisubstituted 1H-imidazole-3-oxides 1 with 2,2-bis(trifluoromethyl)ethene-1,1-dicarbonitrile (7, BTF) yielded the corresponding 1,3-dihydro-2H-imidazol-2-ones 10 and 2-(1,3-dihydro-2H-imidazol- 2-vlidene)malononitriles 11, respectiv
