It was observed that the optimum temperature for the fluorous biphasic regioselective nitrations of toluene, ethylbenzene, flurobenzene, chlorobenzene, bromobenzene, odobenzene and diphenyl ether were 80℃, 60℃, 60℃, 60℃, 80℃, 80℃ and 70℃ respectively. The catalyst had almost no activity when the reaction system contained 25% of water. Simultaneously, increasing the volume ratio of fluorous phase and organic phase in the system in which the fluorous phase can miscible with organic phase could decrease ortho-para ratio.
