7.1: Oxidation-Reduction Reactions of Organic Compounds- An Overview The reagent to be used for any given transformation must be chosen carefully in order to ensure that only the desired functional group or groups is effected: some reducing agents, for example, will act on ketones and aldehydes but leave alkenes and carboxylic acid derivatives untouched, while other will reduce all of these functional groups. 7.2: Reduction Reactions 7.3: Chemoselective Reactions 7.4: Oxidation of Alcohols 7.5: Oxidation of Aldehydes and Ketones 7.6: Oxidation of Alkenes to 1,2 Diols
