查询词典 oxidants

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.
