Researchers have always been intrigued by one-step selective hydroxylation of aromatic compounds since achieving adequate selectivity toward the target product and avoiding overoxidation are challenging. However, the naturally available oxygenase enzymes efficiently and selectively perform such transformations under normal atmospheric conditions. Inspired by naturally occurring oxygenase enzymes, researchers have undertaken numerous attempts to catalyze the oxidation of arenes using homogeneous and heterogeneous catalysts. In this regard, the first-row transition metal complexes are considered as candidates due to their abundance and redox characteristics. Therefore, this review focuses on catalyst design strategies to improve the efficiency and selectivity of arene oxidation and illustrates the distinctive homogeneous approaches reported in this area by employing first-row transition metal complexes.

第一行过渡金属配合物作为芳烃氧化催化剂的合理设计：一种均相方法

研究人员一直对芳香族化合物的一步选择性羟基化很感兴趣，因为实现对目标产物的足够选择性并避免过度氧化具有挑战性。然而，天然可用的加氧酶在正常大气条件下有效且选择性地进行此类转化。受天然存在的加氧酶的启发，研究人员进行了多次尝试，以使用均相和多相催化剂催化芳烃的氧化。在这方面，第一行过渡金属配合物因其丰度和氧化还原特性而被认为是候选者。所以，
