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 ...

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 ...

Cyclopropanes are a common motif in medicinal chemistry. Three-carbon rings show up in drug structures for conditions including asthma, psoriasis, and COVID-19. But despite its utility, cyclopropane ...

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.

Complete combustion of alkenes produces carbon dioxide and water, provided there is a plentiful supply of oxygen. Incomplete combustion of alkenes occurs where oxygen is limited and produces water, ...
