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.

Researchers are searching for better alternatives to this approach. "It would be better to directly use dinitrogen and alkenes to synthesize alkyl amines under mild conditions," he adds.

Enantioenriched alkyl–alkyl bonds are produced from abundant alkenes in one step via Ni-catalysed asymmetric cross-hydrodimerization. This technique overcomes the reactivity and selectivity ...

Taking inspiration from enzymes, chemists at the University of Illinois Urbana-Champaign developed a catalyst to simplify the synthesis of ethers, key functional components of many drugs, foods, ...

A new enzyme-inspired, small-molecule catalyst developed at the University of Illinois holds alcohols and alkenes in just the ...
