Two ChemComm Viewpoints on calixarenes and cations

11 Jul 2013

Our Viewpoints focus the spotlight on significant impacts and breakthroughs resulting from ChemComm articles in the last century, and can serve as catalysts for active discussion and inspiration within the community.

Earlier this year, Jack Harrowfield’s Viewpoint focussing on the 1985 contribution of Tony McKervey’s group to the field of calixarenes and cations generated an enthusiastic response, including suggestions on other articles that were also felt to have played a seminal role in calixarene chemistry. As a result, we have recently published an alternative Viewpoint by Alessandro Casnati on the impact of Communications published (in 1983 and 1984) by the group of Rocco Ungaro and Andrea Pochini.

Read both Viewpoints now and see the impact these groundbreaking Comms created:

Calixarenes and cations

Alessandro Casnati
Chem. Commun., 2013, 49, 6827-6830

Synthesising gold- and silver-NHC complexes using a weak base

24 Jun 2013

Scientists from the University of Zaragoza in Spain have developed a simple and efficient method of synthesising N-heterocyclic carbene (NHC) gold and silver complexes with the use of an extremely weak base¹.

Gold-NHC complexes are commercially important precursors of active, luminescent species that catalyse many useful reactions, such as cycloisomerisation, rearrangement of allylic acetates, C-H activation, carbene transfer, polymerisation, among others. In addition, they have potentially significant applications in the synthesis of new pharmaceuticals and natural products.

Conventional methods of gold-NHC synthesis– the generation of free NHC and the Ag-carbene transfer route– present several logistic and economic limitations, such as the need for an inert atmosphere and the use of additives. These methods are not always efficient, and typically require complicated working conditions in order to produce even moderate yields.

M. Concepción Gimeno and her team’s novel and elegant one-pot synthetic route involves isolating imidazolium salts using [AuCl(tht)] (tht = tetrahydrothiophene) in the presence of a mild base, such as K₂CO₃, to produce gold-NHC complexes with very high yields (91-94%) over relatively short reaction times (1.5 hours).

c3cc42919a-s2

Similarly, Gimeno et al. found that, using the same mild base protocol, silver-NHC complexes could also be efficiently synthesised using AgNO₃, with vast potential significance in transmetalation.

c3cc42919a-s3

In both routes, the reactions occur under ambient conditions, eliminating the need to work in an argon atmosphere, and using readily-available technical grade solvents.

Interestingly, a mere few days later, Gimeno et al.‘s groundbreaking work was followed closely and independently by a related Communication from Steven Nolan’s group at the University of St Andrews. In addition to testing a similar methodology, Nolan’s team compared small- and larger-scale reactions, and characterised compounds by ¹H and ¹³C{¹H} NMR spectroscopies, as well as by elemental analysis².

Do you know how chemical scientists can tackle global challenges in Human Health? If so, the RSC is running a one minute video competition this summer for young researchers such as PhD and Post-doc students; get involved and innovate the way scientists share their research. Your video should communicate your own personal research or an area of research that interests you, highlighting its significance and impact to Human Health.

Five videos will be shortlisted by our judging panel and the winner will be selected during the ‘How does chemistry keep us healthy?’ themed National Chemistry Week taking place 16-23 November.

A £500 prize and a fantastic opportunity to shadow the award winning video Journalist, Brady Harran, is up for grabs for the winner.

The judging panel will include the makers of The Periodic Tale of Videos, Martyn Poliakoff and Brady Harran, and RSC Division representatives.

Check out our webpage for further details of the competition and an example video.

Closing date for entries is 01 July 2013. Please submit your entries to rsc.li/take-1-video-competition.

Photocatalysis in a nanocup

13 May 2013

Written by Geoff Nelson, web writer.

Nanocups of anatase TiO2 coated with Au nanoparticles are efficient photocatalysts, as reported in a recent ChemComm article by Chemical Science and Chem Soc Rev Advisory Board member Jinlong Gong and his group at Tianjin University, China.

This new shape promises to increase reactive surface area by exposing the normally inaccessible surface of hollow spheres. Compared to TiO2 hollow spheres, TiO2 nanocup particles increase the rate of the photocatalytic degradation of methylene blue in the visible light region by 46%.

This performance and the ease of nanocup synthesis are reasons to promote further research. Thus, we may expect nanocups made from other metal oxides and inorganic materials to be incorporated into solar, photochemical, and catalytic applications in the future.

In addition, the ability of nanocups to confine small amounts of reactants may find utility in nanofluidic devices.

Gong et al.‘s work has recently been highlighted as part of a C&EN article on novel nanostructures.
