Riley oxidation - Wikipedia

MechanismScopeAppli ionsThe mechanism of oxidation of -CH2C O R group by SeO2 has been well investigated. The oxidation of carbonyl alpha methylene positions begins with attack by the enol tautomer at the electrophilicselenium center. Following rearrangement and loss of water, a second equivalent of water attacks the alpha position. Selenic acid is liberated in the final step to give the 1,2-dicarbonyl product. Allylic oxidation using selenium-dioxide proceeds via an ene reaction at the electrophilic selenium center. A 2,3-sigmatro…

Redox - Wikipedia

EtymologyDefinitionsOxidizing and Reducing AgentsStandard Electrode PotentialsExamples of Redox ReactionsRedox Reactions in IndustryRedox Reactions in BiologyRedox Reactions in GeologyRedox Reactions in SoilsBalancing Redox Reactions"Redox" is a portmanteau of the words "reduction" and "oxidation". The word oxidation originally implied reaction with oxygen to form an oxide, since dioxygen O2 g was historically the first recognized oxidizing agent. Later, the term was expanded to encompass oxygen-like substances that accomplished parallel chemical reactions. Ultimately, the meaning was generalized to include all processes involving the loss of electrons. The word reduction originally referred to the loss in weight upon heating a metalli…
