Alkenes undergo a number of reactions in which the C=C double bond is oxidized. For organic compounds, a conventional way to tell whether the oxidation or reduction occur is to check the number of C–O bonds or the C–H bonds. An oxidation reaction increase the number of C–O bonds or decrease the number of C–H bonds.

In the laboratory, alkenes are oxidized to give epoxides on treatment with a peroxyacid, RCO 3 H, such as meta -chloroperoxybenzoic acid. An epoxide, also called an oxirane, is a cyclic ether with an oxygen atom in a three-membered ring.

Through the summary and expansion of these reactions, this article aims to help students master these key reactions while fostering their research interests and encouraging them to engage with cutting-edge scientific challenges.

Alkenes can be cleaved by oxidation with ozone, O 3., using a process called ozonolysis. The carbon-carbon double bond is broken, and the alkene carbons are converted to aldehydes: Dimethyl sulfide or zinc is added in the work-up stage of the reaction in order to reduce hydrogen peroxide, which is formed in the reaction, to water.

2025年1月4日 · Alkenes can be oxidised by cold dilute and hot concentrated KMnO4 to give different products. The above reactions can be used to predict where the double bond in a larger molecule is. What are the products of the oxidation of 2-methylprop-1-ene with hot, concentrated acidified KMnO 4 (aq)? Answer:

There are a variety of oxidative reagents that can react with alkenes. These reagents oxidize the alkene to different degrees and have different synthetic applications. It can be helpful to describe the relative oxidative strength of the reagents. Some reagents are so strong that the carbon chain will be cleaved at the alkene.

2025年2月20日 · Herein we describe the oxidation of alkenes to carbonyls and acetonides via the interplay of photoexcited nitroarenes and Lewis acid catalysis. A wide range of alkenes were oxidized to aldehyde and ketone products with anti-Markovnikov selectivity and to acetonides when acetone was employed as a co-solvent. Mechanistic studies support that Lewis acid coordination to the 1,3,2-dioxazolidine ...

2013年3月28日 · Hydroboration-oxidation is a useful and important method for forming alcohols from alkenes. The reaction involves treatment of an alkene (also known as an olefin) with a borane (a neutral molecule containing a B-H bond).

In organic chemistry, identifying oxidation and reduction reactions often involves tracking changes in the bonding around carbon atoms. We can approach this in two ways:
