Homogeneous catalysis

Definition

Homogeneous catalysis is a type of catalysis in which the catalyst operates in the same phase as the reactants — usually dissolved in a solvent. Mechanistic studies of homogeneous catalysts are generally easier than those of heterogeneous catalysts, which aids optimization. They can, however, be difficult to separate from the products and thus recycle.

    A unique transformation for the site-selective cleavage of one C–C single bond and two C–H bonds in sequence has now been developed. This enables a simple carbon skeleton to be reorganized into a significantly more complex form with remarkable efficiency.

    Three different methods that use a single ruthenium catalyst to enable the facile formation of meta- and para-substituted alkenylarenes have now been developed. The reactions proceed through a tandem alkenylation/decarboxylation process and provide several advantages over alternative approaches.

    Carbonyls and alkenes, two of the most common functional groups in organic chemistry, generally do not react with one another. Now, a simple Lewis acid has been shown to catalyse metathesis between alkenes and ketones in a new carbonyl olefination reaction.

    The oxidation of water is essential to the sustainable production of fuels using sunlight or electricity, but designing active, stable and earth-abundant catalysts for the reaction is challenging. Now, a complex containing five iron atoms is shown to efficiently oxidize water by mimicking key features of the oxygen-evolving complex in green plants.
