Chemical groups containing oxygen, nitrogen, silicon, and other heteroatoms often react during alkene coupling reactions, generating undesirable product mixtures. But a new, iron-catalyzed radical ...

Chemists from the National University of Singapore (NUS) have developed a straightforward method to convert common chemicals like carboxylic acids, alcohols, and alkanes directly into valuable alkenes ...

Asymmetric ring‐opening reactions of bicyclic alkenes have emerged as a transformative approach in modern synthetic chemistry. These reactions capitalise on the inherent ring strain of fused cyclic ...

Bromine water is an orange solution of bromine. It becomes colourless when it is shaken with an alkene. Alkenes can decolourise bromine water, but alkanes cannot. The slideshow shows this process.

Looking to turn simple alkenes into more complex molecules, chemists at Colorado State University report a stereospecific carboamination of C=C bonds. The reaction provides a new way to synthesize ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 103, No. 42 (Oct. 17, 2006), pp. 15349-15354 (6 pages) Single-site polymerization catalysts enable exquisite ...

A dilute solution of bromine is added to samples of heptane and cyclohexene. The bromination reactions and mechanisms are compared. UV light splits the bromine molecule into two reactive radicals, ...

The second homologous series is the alkenes. Their names all end in –ene, for example ethene. Alkenes all contain a carbon to carbon double bond which makes them more reactive than the alkanes. The ...
