Hydrogenation reactions in micelles

Can hydrogenation reactions be performed in water? German scientists say: “Yes we can!”

Often, water is seen as the “green solvent” of choice as it is non-flammable and non-toxic. However, organic chemists usually face issues with the solubility of the reactants in water. In this RSC Advances article, Schwarze et al. demonstrate the power of the surfactants in a hydrogenation reaction of prochical C–C, double bonds in itaconate, e.g. dimethyl itaconate.

The selectivity were comparable to when the same reaction were performed in methanol. The reaction rates however were slightly slower. This was due to the lower hydrogen solubility in the micellar aqueous systems. But the beauty of the reaction is that no notable catalyst deactivation occurred and the latter was recyclable with a turn-over number of >1000 in the aqueous micellar conditions .

In this publication, the authors also developed a model to predict the performance of micellar reaction systems. The partition coefficient of the substrates between the micelles and the continuous aqueous phase can be predicted using the Conductor-like Screening Model for Real Solvents (COSMO-RS).

Where can I meet the RSC Advances team?

Over the coming months, members of the team will be at the following conferences where they will be happy to talk to you:

  • James Batteas, Associate Editor, will be at the Fall ACS meeting in Denver at the end of the month. Look for RSC Booth 1100! Lots of prizes to be won each day, incl. T-shirts, games & books.

 

 

  • Kathleen Too, Deputy Editor, travels to the 14th Asian Chemical Congress 2011 (14 ACC) taking place between 5-8 September 2011 in Bangkok, Thailand. Please contact us if you’d like to arrange a meeting.

 

  • Mike Ward, Chair of the Editorial Board, is attending the 3rd Asian Conference on Coordination Chemistry (ACCC3) in New Delhi, India at the end of October. An RSC Advances poster prize will be awarded at this meeting.

And look out for our eye-catching RSC Advances materials, appearing at a variety of conferences over the coming months.

RSC Advances Issue 1 published

From Argentina to New Zealand, Korea to USA, scientists around the world have shown their support for RSC Advances by submitting their work. Our first issue is online now and access is free.*

Communications, full papers and reviews are all represented in the mix that encompasses all the main areas of the chemical sciences. But finding the articles that are most relevant to you won’t be a problem: our sophisticated behind-the-scenes topic modelling classifies the content into one or more of twelve subject categories, accessible via the subject tab on the website. 

Among the highlights in this issue:

Marcos Eberlin, who is one of RSC Advances’ Associate Editors, has demonstrated his support through publishing his work on charge-tagged N-heterocyclic carbenes.

Of the first issue Marcos commented: “Very nice collection indeed … The subject tab is superb!”

Plus, Editorial Board Chair Mike Ward and RSC Publishing Editor Sarah Ruthven share their aspirations for the journal in the Editorial
