Autoxidation (sometimes auto-oxidation) refers to oxidations brought about by reactions with oxygen at normal temperatures, without the intervention of flame or electric spark. The term is usually used to describe the gradual degradation of organic compounds in air at ambient temperatures. Many common phenomena can be attributed to autoxidation, such as food going rancid, the 'drying' of varnishes and paints, and the perishing of rubber. It is also an important c…

WebRXNO:0000029. In organic chemistry, the oxy-Cope rearrangement is a chemical reaction. It involves reorganization of the skeleton of certain unsaturated alcohols. It is a variation of the Cope rearrangement in which 1,5-dien-3-ols are converted to unsaturated carbonyl compounds by a mechanism typical for such a [3,3]- sigmatropic rearrangement. hrweb backup careAls Ether (in der Gemeinsprache auch Äther ) werden in der Chemie organische Verbindungen bezeichnet, die als funktionelle Gruppe eine Ethergruppe – ein Sauerstoffatom, das mit zwei Organylresten substituiert ist – besitzen (R –O–R ).
