In this study, convenient and selective oxidation of alcohols using aqueous hydrogen peroxide to yield carbonyl compounds was studied. Using the ruthenium-(4-methylphenyl-2,6-bispydinyl) pyridinedicarboxylate complex [Ru(mpbp)(pydic)] as a catalyst, primary and secondary alcohols were oxidized to aldehydes and ketones at room temperature with a satisfactory yield and excellent selectivity. The influence
在这项研究中,研究了使用过氧化氢水溶液方便而选择性地氧化醇以生成羰基化合物的方法。使用钌-(4-甲基苯基-2,6-双吡啶基)吡啶二甲酸配合物[Ru(mpbp)(pydic)]作为催化剂,伯醇和仲醇在室温下被氧化成醛和酮,具有令人满意的收率和优异的选择性。还评估了各种反应参数(例如溶剂,催化剂和氧化剂的量)对活性和选择性的影响。动力学研究表明,醇的氧化就底物和过氧化氢而言是一阶的,而对于催化剂而言则是二阶的。在原位的基础上,提出了一种涉及具有亲电性质的钌-氧代物种的合理机制。 紫外可见光谱研究和哈米特图。
