Advances on the development of new oxidation reagents and methodologies and their applications in both target-and diversity-oriented synthesis have been regularly surveyed and constituted one of the most extensively and actively investigated areas of current organic synthesis.1 In this context,a plethora of oxidants,including those small organic molecule-based reagents (such as Dess-Martin periodinane,Swern oxidation,Moffatt oxida- tion,Corey-Kim oxidation,and 三氧化硫/pyridine)and metal-based systems(such as Jones reagent,Collins reagent,pyridinium chlorochromate,pyridinium dichromate,barium permanganate, manganese dioxide,ruthenium tetroxide,silver carbonate,and Oppenauer oxidation),have been identified to be powerful tools promoting conversion of various alcohols into their corresponding aldehyde or ketone products and thus evolved as a most important class of tools in synthetic chemists'arsenal.

关于新的氧化试剂和方法，在两个目标和多样性为导向的发展及其应用合成的进步定期调查，构成一个最广泛，积极探讨在这方面，过多的地区目前有机合成。1氧化剂，包括有机小分子为基础的试剂（如Dess - Martin氧化剂，斯文氧化反应，氧化法特，科里，金氧化，三氧化硫/吡啶）和金属为基础的系统（如琼斯试剂，柯林斯试剂，吡啶氯铬，吡啶铬，钡锰，二氧化锰，四氧化钌，银碳酸盐和开瓶器氧化），已被证实为推动中相应的醛或酮醇转化的各种产品，功能强大的工具，因而作为一个最重要的阶级演变在阿森纳的工具合成化学家。
