structure) hydroxylates phenols with O2 via a stable side‐on peroxide complex, which is similar to the active site of tyrosinase in terms of the ligand environment and its spectroscopic properties. The catalytic oxidation of phenols to quinones proceeds at room temperature in the presence of NEt3 and even non‐native substrates can be oxidized catalytically. The reaction mechanism is analogous to that
一种新的催化剂(见结构)通过稳定的侧向过氧化物络合物将酚与 O 2羟基化,在配体环境及其光谱特性方面类似于酪氨酸酶的活性位点。在室温下,在 NEt 3存在下,苯酚催化氧化为醌,甚至非天然底物也可以催化氧化。反应机理类似于酶催化反应。
