A study about the oxidative coupling of some representative carbo- and heterocyclic non-symmetrical quinones with aryl- and alkylamines, was carried out comparing dichloromethane and water as reaction mediums. We found that the on-water reactions gave better or, at worst, the same results as a conventional organic medium like dichloromethane. Descriptors derived from conceptual density functional theory
比较了二氯甲烷和水作为反应介质,对一些代表性的碳和杂环非对称醌与芳基和烷基胺的氧化偶联进行了研究。我们发现,与常规有机介质(如二氯甲烷)相比,水上反应产生的效果更好,或更糟。从概念密度泛函理论和静电性质方法(例如分子静电势)派生的描述符用于解释观察到的化学反应性和区域选择性。此外,在水上条件用于获得24种具有潜在生物活性的新氨基醌。
