Olefins

The alpha-olefins, consisting of carbon and hydrogen, are the most important precursors in the chemical industry. Researchers at the University of Bayreuth present a discovery in the journal “Science” that opens up previously unimagined prospects for the design and the selective as well as sustainab more

It sounds like modern-day alchemy: Transforming sugar into hydrocarbons found in gasoline. But that’s exactly what scientists have done. In a study in Nature Chemistry, researchers report harnessing the wonders of biology and chemistry to turn glucose (a type of sugar) into olefins (a type of hydroc more

An electrochemical approach developed at KAUST produces molecular-sieving membranes that could enable a cheap energy-efficient separation of light hydrocarbons, such as olefins and paraffins. This separation, critical for the petrochemical industry, usually relies on extremely energy-intensive proce more

A green strategy was developed for synthesis of various value-added chemicals using methanol, acetonitrile, acetic acid, acetone and ethyl acetate as the hydrogen source by coupling them with olefins over heterogeneous photocatalysts. A radical coupling mechanism was proposed for the hydrofunctional more

Hydroaminomethylation of olefins with H2O as hydrogen source was accomplished over an Ir-catalyst with the involvement of an ionic diphosphine (L6). The use of H2O as the hydrogen source could completely inhibit the hydrogenation of olefins. The π-accepting ability and improved stability of L6 rende more

Here, surprising results are presented in bulk Pd catalyzed carbonylation reactions. Three types of carbonylation reactions can be realized efficiently under organic ligand-free conditions, i.e., hydroaminocarbonylation of olefins, aminocarbonylation of aryl iodides and oxidative carbonylation of am more
