A major advance in alkene oligomerization catalysis was Brookhart’s 1995 report of highly active group 10 metal diimine systems. In contrast to nickel and palladium catalysts, the corresponding ...

The researchers used an easily accessible and reusable chemical called vinyl ketone as the "olefination reagent" to help create alkenes. By fine-tuning the reaction parameters of the vinyl ketone ...

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.

Tonight, it will be dry with large areas of cloud about, and just a few clear breaks for some. A few patches of mist and fog may form locally. Light winds. Friday Tomorrow will remain largely dry ...

For example, ethene reacts with water (in the presence of heat and a catalyst) to produce the alcohol ethanol. Addition polymerisation uses addition reactions to turn alkenes into polymers.
