The Rubottom oxidation is a useful, high-yielding chemical reaction between silyl enol ethers and peroxyacids to give the corresponding α-hydroxy carbonyl product. The mechanism of the reaction was proposed in its original disclosure by A.G. Brook with further evidence later supplied by George M. Rubottom. After … Visa mer In 1974, three independent groups reported on the reaction now known as the Rubottom oxidation: A.G Brook, A. Hassner, and G.M. Rubottom. Considerable precedent for the reaction already existed. For … Visa mer The Rubottom oxidation has remained largely unchanged since its initial disclosure, but one of the major drawbacks of standard conditions is the acidic environment, which can lead to unwanted side reactions and degradation.
