Getting rid of nasty chloro-phenols
Chlorophenols are highly toxic compounds, used as pesticides and disinfectants, for which oxidation by hydrogen peroxide is the prime treatment process. Gábor Lente, University of Debrecen, Hungary, and James Espenson, Iowa State University, US, have studied the kinetic efficiencies of several iron catalysts in this reaction. They compared efficiencies using a standardized set of simple experiments-rather than using only one catalyst and more complex analytical procedures-to determine the best catalyst taking several different requirements into account.
Tag with biomolecule
Herman Overkleeft and colleagues at Leiden University, The Netherlands, and Harvard Medical School, US, survey chemical labelling techniques as tools in the study of biomolecules. Examples include the use of chemically modified metabolic precursors, the tagging of fusion proteins with synthetic probes and the tagging of enzymes with activity-based probes. The researchers emphasise the potential application of these techniques in fundamental biochemistry, pharmaceutics and medicine.
No protection required
Thomas Kaden and co-workers at the University of Basel, Switzerland, have developed a route to new difunctionalized macrocycles without the need for costly protection steps. Addition of hydride to a copper macrocycle containing two identical side chains results in only one of the side chains being modified. The hydride ligand is key to the reaction as it not only instigates the process but also binds the end-product ensuring that the other side chain does not react.
World's smallest test tube
Verified in the Guinness Book of World Records as the world's smallest test tube, David Britz and colleagues from the University of Oxford and the University of Nottingham, UK, have carried out reactions to form linear, unbranched polymers inside a single-walled carbon nanotube. With a diameter of approximately 1.2 nanometres and a length of 2 micrometers, the total volume of the vessel is one yoctolitre (10-24 litres). The resulting 'peapod' structure offers new routes for the synthesis of novel materials.
