C-H activation: an article collection

Picture showing several chemical reaction schemes and moleculesOne of the simplest and most utilised chemical reactions is the burning of hydrocarbons and while combustion is an excellent way to exploit the energy content of this naturally occurring resource, there is a lot more we can do with the ‘inert’ C-H bond.

C-H activation allows us to convert cheaper hydrocarbon starting materials into more valuable and versatile products; leading to the development of a wide range of reagents and catalysts that activate C-H bonds. To keep you up to date with the latest developments in the field we have created this article collection, where all articles are free to download until 15th December.

Biocatalysis: an article collection

A picture of an enzymeBeers, wines and cheeses are enjoyed around the world today and have been for millennia. In fact the practices of brewing and cheese-making pre-date recorded history so it is difficult to accurately determine when we first started using naturally occurring enzymes and microorganisms to create valuable (and in this case, tastier!) products.

Biocatalysts are of course used in far more diverse applications than the creation of food-stuffs, including in many organic syntheses and in the generation of fine chemicals. Due to their natural design, they can offer superior selectivity for particular products and have a far lower environmental impact than many traditional catalysts. Our knowledge and understanding of biocatalysts has increased dramatically in the last few decades, which has allowed us to develop biologically modified and biomimetic catalysts for a range of applications.

To keep you up to date with the latest advances in this rapidly expanding field we have collected together these high impact articles and made them free to access until the 31st October!

Organometallics in catalysis: an article collection

Perhaps the most well-known applications of organometallics in catalysis are the Ziegler–Natta catalysts which are used to generate polymers, the catalysts are made up of mixtures of transition metal halides and organo-aluminium complexes. Karl Ziegler and Giulio Natta were awarded the 1963 Nobel Prize in Chemistry for their discovery and development of the catalysts, which today are the most commonly used for the manufacture of polythene.

The esteemed history of organometallics are not to be under-estimated and include Grignard’s reagents, the Heck reaction, Schrock catalysts, Grubbs’ catalysts and the Suzuki Coupling to name just a few. Organometallic compounds have revolutionised science and industry and to keep you up to date with the latest break-through research being made across all areas of organometallics in catalysis, we have made this cross-journal article collection free until the 26th September.

Incredible ionic liquids: an article collection

Ionic liquids are pretty self explanatory; they are ionic materials in a liquid state. In a ‘normal’ liquid, interactions are usually governed by Van de Waals or H-bonding forces. In ionic liquids it is ionic bonding interactions which dominate, meaning ionic liquids possess some interesting and unique properties.

The field of ionic liquids grew after Paul Walden’s observations of ethylammonium nitrate in 1914,1 since then the study and use of ionic liquids has grown phenomenally, with applications in analytics, biology, electrochemistry, physical chemistry, engineering, solvents and catalysis.

The academic and industrial interest in ionic liquids has thrown up some remarkable discoveries, particularly in recent years, so to keep you up to date with latest break-through research in the field we have collected these high quality articles which are free to access!* Click here for the full list of free articles
