Unexpected palladium catalyzed O-arylation occurring in 4-(4-fluoro-3-nitrophenyl)-1,2-dimethyl-5-nitro-1H-imidazole series

We describe herein a new unexpected palladium-catalyzed O-arylation reaction in fluorinated nitro(o-nitrophenyl)imidazole series involving arylboronic acids under Suzuki–Miyaura cross-coupling reaction conditions.
