Featured Journal – Chemical Communications

Image

This edition of Featured Journal is one of my personal favourites – Chemical Communications, or Chem Comm.

With an impact factor of 6.378, Chem Comm is a journal which specialises in the rapid publications of significant developments in the chemical sciences. The speed of publications is shown by the fact that this journal puts out 100 issues per year, and only high-quality chemistry research is shown.

Chem Comm features communications from all areas of chemistry, providing a great tool for chemists to find recent cutting edge research in their field. The nature of the journal means that there is always something interesting to read about, and I personally found it difficult to pick out articles to highlight.

You can find the latest addition here, although you will need a membership to the RSC or a subscription via a university to see all of the content.

In Chem Comm today:

“Anthrocene-bisphosphonate based novel fluorescent organic nanoparticles explored as apoptosis inducers of cancer cells”

Anti-cancer chemistry is always going to be a hot topic, with successful cancer remedies being highly sought after by the chemistry community at large. This article reports the use of an organic nanoparticle, based on anthrocene, which self-assembles to form a fluorescent cancer-killing particle which doesn’t harm normal cells in the body. This is an exciting development in anti-cancer therapy, and will hopefully pave the way to new, effective cancer treatments.

“A new versatile class of hetero-tetra-metallic assemblies: highlighting single-molecule magnet behaviour”

Single molecule magnetism is becoming a major subset of coordination chemistry, and coordination compounds which exhibit single molecule magnetism are of great interest at the moment. This article describes the synthesis of a series of very interesting coordination compounds containing 4 metal centres using cyanide ligands. These compounds show interesting magnetic and photochemical activity, and are in themselves a very interesting new type of inorganic compound.

Electrochemistry of AuII AuIII Pincer Complexes: Determination of the Au(II)-Au(II) Bond Energy

I chose to highlight this article because I watched a presentation by one of the authors, Dragos Rosca, at the Coordination Chemistry Discussion Group Meeting in July, and it was really great work. Gold chemistry is fairly underdeveloped compared with many of its transition metal neighbours, and is dominated by complexes featuring gold in its +1 or +3 oxidation states. The authors have synthesised a really neat complex containing an unsupported gold(II)-gold(II) bond using a pyridyl pincer ligand, and this article describes the use of electrochemistry to determine its bond energy. I’ve recently undertaken a postgraduate course in electrochemistry, and it really is interesting. It goes on to describe the use of cyclic voltammetry to determine the reduction pathways of similar LAu-H and LAu-OH complexes. This is really nice coordination chemistry and a great demonstration of the utility of electrochemical techniques.

“A Novel Protecting Group Methodology for Syntheses Using Nitroxides”

Most organic chemists will be more than familiar with the use of protecting groups for the preservation of certain moieties whilst carrying out transformations elsewhere in a molecule. Although they require the use of extra steps and reagents in syntheses, they are often necessary and crucial for keeping part of a molecule safe from attack by a chemical reagent. Here, we see the protection of the nitroxide functional group, which has many applications in areas such as materials science and medicine. The protection involves the use of the relatively simple methoxyamine group, which can then be cleaved in good yield using meta-chloroperoxybenzoic acid (mCPBA). This simple and effective new methodology will no doubt assist synthetic chemists everywhere in their pursuit of new nitroxide-containing molecules.

With its great deal of variety and high publication output, Chem Comm always makes for a good read. Personally, I find it to be one of the most interesting general chemistry publications, and the fact that most of its articles are relatively short makes it easy to breeze through and find what is most relevant and appealing to you. Give it a go!
