Dess-Martin试剂的制备及在氧化环己醇中的应用

Preparation of Dess-Martin Reagent and Its Application in Oxidizing Cyclohexanol

环己酮的制备是化学类本科教学实验中经典的有机化学“操作型”实验,也是为数不多的氧化类有机实验。但使用的氧化剂均为非绿色的高价重金属氧化剂,教学过程局限于培养学生的实验操作能力。鉴于此,我们将实验改进为设计型实验,要求学生查阅文献,调研并探寻更为绿色环保的氧化体系,通过评估多种氧化体系的优劣性,确定氧化剂类型,设计实验方案并完成实验。该改进措施提高了实验的高阶性、创新性和挑战度,在扎实训练学生实验操作技能的同时,不仅培养了学生发现、分析和解决问题的能力,还能促进学生建立创新思维与绿色化学意识。

Preparation of cyclohexanone is a classic“hands-on”organic chemistry experiment widely used in undergraduate teaching.However,conventional experiments often involve the use of non-environmentally friendly high-cost heavy metal oxidants,limiting the teaching process to the development of students’experimental skills.In response to this,we have transformed the experiment into a design-oriented approach.Students are tasked with consulting literature,researching,and exploring greener and more environmentally friendly oxidation systems.By evaluating the merits of various oxidation systems,determining the types of oxidants,and designing experimental procedures,students complete the experiment.This innovative approach enhances the experiment’s complexity,promotes innovation,and introduces challenges.It not only solidifies students’practical laboratory skills but also cultivates their ability to discover,analyze,and solve problems,fostering innovative thinking and awareness of green chemistry.
