The first step of the mechanism of this reaction involves the S N 2 attack of the Grignard reaction to open the epoxide to form an alkoxide.
Web28 jan. 2024 · A common method for oxidizing secondary alcohols to ketones uses chromic acid ( H2CrO4) as the oxidizing agent. Chromic acid, also known as Jones reagent, is prepared by adding chromium trioxide (CrO 3) to aqueous sulfuric acid. WebPeroxycarboxylic acids are generally unstable. An exception is meta-chloroperoxybenzoic acid, shown in the mechanism above. Often abbreviated MCPBA, it is a stable crystalline solid. Consequently, MCPBA is popular for laboratory use. However, MCPBA can be explosive under some conditions.
