Although univariate methodologies facilitate the interpretation of results, they may not correspond to the ideal conditions for a catalytic process. Herein, we examine the catalytic activity of an iron(III) (1) and a copper(II) (2) complex under mild conditions in the oxidation of cyclohexane (Cy) and benzyl alcohol (BnOH) with hydrogen peroxide, following a Box–Behnken multivariate experimental design. To the best of our knowledge, this is the first report of the application of this tool to the homogeneous oxidation of these organic substrates. The multivariate approach allowed a range of optimal conditions to be identified for the variables studied. Complex 1 was able to convert higher amounts of the studied substrates into products when compared with 2. However, 2 presented higher selectivity toward the generation of cyclohexanol (CyOH) and benzaldehyde (BA) than 1, although the conversion rates were lower.

多变量分析应用于单核铁和铜络合物促进的环己烷和苯甲醇的氧化

尽管单变量方法有助于结果的解释，但它们可能不符合催化过程的理想条件。在此，我们研究了铁（Ⅲ）（1）和铜（Ⅱ）（2）配合物在温和条件下用过氧化氢氧化环己烷（Cy）和苯甲醇（BnOH）后的催化活性。–Behnken多元实验设计。据我们所知，这是该工具在这些有机基质的均匀氧化中应用的第一份报告。多元方法允许为研究的变量确定一系列最佳条件。综合大楼1与2相比，它能够将更多数量的被研究底物转化为产品。然而，2呈现朝向（CyOH）比代环己醇和苯甲醛（BA）具有更高的选择性1，虽然转化率较低。
