In this Dalton Transactions Hot article, ionic liquids are made by reactive distillation.
Peter Licence and co-workers from the University of Nottingham discovered this method by accident while researching [C4C1Im][BF4], when they realised that the substance they had after distillation was very different to their starting materials. Further investigation revealed they had created a borane-substituted imidazol-2-ylidene, a compound with potential to be an excellent solvent for a wide variety of reactions.
The conventional technique to make these type of ionic liquids is via a direct nucleophilic reaction, which is experimentally difficult as the starting reagents are highly reactive. This distillation technique is particularly good, not only because of the stability and availability of the starting materials, but because of the high purity of the obtained products.
Read on to find out more details about this technique.

In this Dalton Transactions Hot article, calcium silicate microparticles doped with rare earth ions were loaded with ibuprofen and tested for their drug delivery properties.
The microparticles showed strong luminescence, which increased as the ibuprofen was released, allowing the drug delivery to be monitored, a highly useful property in therapeutics.

In this Dalton Transactions Hot article, the kinetics of rhodium porphyrin b-hydroxy alkyl reactions in water and DMSO are investigated.
Understanding the mechanics of these types of reaction will lead to better selectivity in catalytic oxidation of alkenes and, as the authors say, ‘may lead to the development of water soluble catalysts’. These can then be used to produce a green form of oxidation chemistry.

In this Dalton Transactions Hot article, researchers at Nanjing University, China have developed a fluorescent sensor to detect the biologically important anion pyrophosphate.
Pyrophosphate in the body is integral to the production of ATP and DNA, and is involved in preventing the formation of hydroxyapatite in extracellular fluid. A lack of pyrophosphate leads to medial calcification, while an excess has been linked to calcium pyrophosphate dihydrate deposition disease, a form of rheumatism.
In this paper the authors make a ratiometric fluorescent sensor using a naphthalene appended tetraazamacrocycle (1)-Zn2+ complex. The sensor is not influenced by its environment, as the ratio of fluorescent intensities at two different wavelengths is measured, rather than using one lone fluorescence, as in the conventional method.

The Editorial Board and team at Dalton Transactions would like to wish all their readers a very merry Christmas.
Dalton Transactions has a great deal to celebrate this coming year, having being publishing for 40 years as of 2011, and achieving an impressive 2009 impact factor of 4.08.
.
Dalton Transactions is 40! Many activities are planned in celebration so keep your eyes peeled on the Dalton Transactions Blog 40th Anniversary Category for more info throughout the year. Look out for our Anniversary Perspective articles from our Editorial Board members.
We will also be celebrating by looking at ‘Top 40s’, the first of which is Dalton Transactions Top 40 cited articles, these will be made free until the end of January. Read the Top Cited Dalton Transactions Articles 40-31 on the blog here: Countdown to the Dalton Transactions 40th Anniversary!
At Dalton Transactions we are delighted with our new impact factor of 4.08. Over four for the first time, many thanks to our readers and authors who have made this possible; read more about this news and visit the Dalton Transactions blog: Highest Ever Impact Factor – 4.1!
The Editorial Board are welcoming a new member, Associate Editor Professor Russell Morris from the University of St Andrews. His expertise is in the synthesis, characterisation and application of porous materials, especially for use in medical applications. Read more about the Editorial Board.
The RSC Publishing offices will be closed over Christmas, from the 25th December until 4th January, but we look forward to your submissions in 2011. Submit your paper online now.
Best wishes and have a safe and happy holiday,
Dalton Transactions Editorial Office
Hiromi Tobita and colleagues look into the reactions of bis(silyl)hydrido molybdenum and tungsten complexes in this Dalton Transactions Hot article. They were able to generate a 16-electron species, which when reacted with nitriles led to hydrosilylation of their CN triple bonds to give N-silylimine complexes, even at room temperature.
