Industrial Catalysts.

Researchers at the University of California Reverside has successfully created a new class of compounds that are karbene very reactive and can be used as a catalyst. Until now the chemists believe that this karbene compounds commonly referred to as "karbene with abnormal N-heterocyclic" or NHCs is not possible to synthesized.

Karbene made of carbon atoms are generally not normally attached to the metal atoms to form metal complexes-karbene which can be used as catalysts in many dibakai pharmaceutical industry, one more thing to note is that compounds have properties that karbene unstable.

Karbene-metal complexes can be made by using two ways: (a) complex was made using a single step without making the first karbene, and (b) metals andcompounds that have been made karbene first reacted to form metal complexes-karbene.

In general, metals used in metal-complex is karbene Rhodium, gold, platinum, or palladium loga-all these are very expensive and toxic by them for making compounds that are made without karbene involving metal compounds but still act as a catalyst merupkan wrong one way to reduce the cost of making these catalysts.

Until sekaranag, is used NHCs using NHCs complexes metal-karbene, and has never been just using it karbene compounds. Chemists assumed that NHCs can not be in the form of elimination, where it makes them believe that without the metal NHCs is not possible in the make. But now UC Riverside's Guy Bertrand, a chemistry professor has turned that assumption because he had been able to create a free NHCs is logamdancompounds can be used to create a variety of other complex compounds.

"Various kinds of chemical species believed to be unstable because they do not meet the stability of the laws we have learned in school and eventually led to the belief that no one tried to make it," said Bertrand, who has led this research.

"After a research task is to unlock the secrets of nature that we may not piker like we have done to make this NHCs and finally we were successful"

NHCs compound this we created stable at room temperature either in solid or solution, this means the application of metal-free compounds is extensive in the industry to be applied to various types of new reactions. This research has been published in "Science October 23, 2009". This publication reported that the synthesis and characteristics of metal-freecompounds NHCs will open a whole new outlook on the world catalyst said John Schwab. "Potential applications for drug discovery and manufacturing processes that caused the real catalyst will lower production costs and environmentally friendly," he said again.

Betrand very interested in the synthesis of NHCs can be made commercially. "We hope to many chemists who can use it to find karbene variety of new applications," he said. UCR Office has registered a patent for this technology and now still looking for partners from industry that will develop this technology commercially. Betrand doing thisresearch with Eugenia Aldeco-Perez, Amos J. Rosenthal, and Bruno Donnadieu of UCR; and Gernot Frenking and Pattiyil Parameswaran of Phillips-Universitat Marburg, Germany, and theresearch was funded by the National Institutes of Health.
