The stronger oxidative reactions cleave the carbon … Alkene to Expoxide Alkene to Epoxide.

As seen with other concerted reactions, it is stereospecific: a cis-alkene will produce a cis-epoxide and a trans alkene will produce a trans-epoxide.

Oxacyclopropane synthesis by peroxycarboxylic acid requires an alkene and a peroxycarboxylic acid as well as an appropriate solvent. Peroxy-acids are commonly used epoxidizing agents. Epoxidation Epoxides are compounds containing a three-membered rimg with oxygen as a heteroatom. Both in the laboratory and in the cell, epoxides are usually formed by the oxidation of an alkene. The epoxidation reaction is where an alkene is subjected to a peroxyacid to convert it into an epoxide. Common Conditions: m-CPBA.
The reaction is initiated by the electrophilic oxygen atom reacting with the nucleophilic carbon-carbon double bond.

(stereochemistry)epoxide from alkene. They have an extra oxygen atom between the carbonyl group and their acidic hydrogen, and are electrophilic at oxygen. These compounds contain an electrophilic oxygen in the OH group and react with alkenes by adding this oxigen to the double bond to form oxacycloprpanes.

The IUPAC name of such rings is oxiran. draw the structure of the diol formed from the reaction of a given alkene … Alkene to Epoxide (m-CPBA) Examples: Example 1. Epoxides have been transformed in good yields to alkenes by a process involving (i) ring‐opening of the epoxide with 2‐mercaptobenzothiazole, (ii) oxidation of the derived β‐hydroxy thioethers to the corresponding sulfones, and (iii) thermal or base‐promoted fragmentation of these sulfones to alkenes. Peroxycarboxylic acids are generally unstable. The are four levels of oxidation for alkenes. Epoxidation of alkenes to form epoxides. CONTROLS . Click on the reaction arrow to visit the page.

Cis alkenes give meso products and trans alkenes give racemic mixtures. Example procedures for the conversion of an alkene to an epoxide using meta-chloroperoxybenzoic acid (m-CPBA). A popular peroxycarboxylic acid is meta-chloroperoxybenzoic acid (MCPBA).

and I want to ask some about (b).
To a solution of the SM (0.48 g, 1.217 mmol) in DCM was added mCPBA (77%, 0.72 g, 3.2 mmol), followed by NaHCO3 (0.24 g, 2.86 mmol) and Na2CO3 (0.24 g, 2.27 mmol). a) Write a mechanism showing the formation of an epoxide from compound A. The mechanism is a concerted reaction between the alkene and peroxyacid.

When an alkene reacts with osmium tetroxide, stereocenters can form in the glycol product. Alkene epoxidation is an exciting reaction in which a double bond reacts with a peroxy acid to form an epoxide.

This process will be discussed in detail in section 10.7. An exception is MCPBA, shown in the mechanism above.
