Abstract

An expedient Rh(III)-catalytic method has been described to synthesis of 2-nitro-2H-azirine derivatives from easily accessible β-nitrooxime ethers via sp3 C–H activation process. This protocol features of low catalyst loading, very mild reaction conditions, and tolerating a diverse of functionalities in good yields. A possible reaction pathway is proposed involving [RhCp*Cl2]2-catalyzed sp3 C–H bond activation and pivalic acid elimination steps.
