Hydroxylation of benzene directly into phenol without converting it into other compounds by using a metal complex-based oxidation catalyst is challenging because of the chemical stability of benzene. We demonstrated that a graphite-supported μ-nitrido-bridged iron phthalocyanine dimer, which acts as a potent iron–oxo-based molecular methane oxidation catalyst, can efficiently catalyze the direct benzene hydroxylation at 25 °C in an aqueous acetonitrile solution containing excess H₂O₂. It was confirmed that the catalytic benzene hydroxidation activity of the graphite-supported μ-nitrido-bridged iron phthalocyanine dimer was significantly higher than that of the silica gel-supported μ-nitrido-bridged iron phthalocyanine dimers.

石墨负载μ-氮化桥联铁酞菁二聚体高效催化苯直接C-H羟基化


由于苯的化学稳定性，使用基于金属络合物的氧化催化剂将苯直接羟基化为苯酚而不将其转化为其他化合物是具有挑战性的。我们证明了石墨负载的μ-氮化桥联铁酞菁二聚体作为一种有效的铁氧基分子甲烷氧化催化剂，可以在25°C下在含有过量H的乙腈水溶液中有效催化直接苯羟基化₂ O ₂ 。证实石墨负载的μ-硝基桥联铁酞菁二聚体的催化苯氢氧化活性显着高于硅胶负载的μ-硝基桥联铁酞菁二聚体。
