Description
Summary:The photo‐induced deoxygenative C2 arylation of quinoline N‐oxides to 2‐arylquinolines is achieved over a heterogeneous porous tubular graphitic carbon nitride (PTCN) catalyst with phenylhydrazines as arylation reagent. A wide range of quinoline N‐oxides can be efficiently transformed into their corresponding 2‐arylquinolines under visible light irradiation. Moreover, PTCN catalyst is easily separated and could be reused several times without loss to its original activity. By using porous tubular graphitic carbon nitride (PTCN) as recyclable heterogeneous catalyst and arylhydrazines as cheap and commercially available arylation reagent, a novel photoinduced deoxygenative C2 arylation of quinoline N‐oxides to 2‐arylquinolines was developed successfully.
