Metal-free C(sp2)-H functionalization of azoles: K2CO3/I2-mediated oxidation, imination, and amination

The direct C2-H oxidation and imination of a wide variety of azoles was achieved by using a commercially available simple K2CO3/I2 reagent combination. The iodinated azole adduct, produced via the in situ generation of N-heterocyclic carbene, is the key intermediate for C2-H oxidation, imination, and amination of azoles. Significantly, these reactions proceed under mild conditions with high to excellent yields, are scalable to large quantity and exhibit a broad substrate scope. Interestingly, this direct C2-H imination method allowed us to access various pharmacologically active N6-alkyl or N6-aryl substituted benzimidazoquinazolinone scaffolds through intramolecular C-H imination in a sequential one-pot reaction.

Halogen-substituted benzimidazolone compounds

New chlorinated and/or brominated N,N'-substituted benzimidazolones are obtained by reacting N,N'-substituted benzimidazolones with chlorine or bromine. The new chlorine-containing and/or bromine-containing benzimidazolone compounds are suitable for the production of heat-stable, flame-resistant polymers.
