New catalytic process could be used to create pharmaceuticals with less chemical waste Much like two children in the back seat of a car, it can be challenging to get two catalysts to cooperate for the greater good. Now Northwestern University chemists have gotten two catalysts to work together on the same task -- something easily done by nature but a difficult thing to do in the laboratory. The findings, published by the journal Nature Chemistry, will allow medicinal chemists to invent new...

Guy Bertrand's lab shows metal-free 'abnormal N-heterocyclic carbenes' are stable, allowing their use in numerous catalytic chemical reactions Researchers at the University of California, Riverside have successfully created in the laboratory a class of carbenes, highly reactive molecules, used to make catalysts "“ substances that facilitate chemical reactions. Until now, chemists believed these carbenes, called "abnormal N-heterocyclic carbenes" or aNHCs, were impossible to make....

Singapore scientists announced they have discovered a way to convert carbon dioxide into clean-burning methanol through a procedure that takes less energy than earlier efforts. The Institute of Bioengineering and Nanotechnology scientists made known Thursday they took non-toxic organocatalysts to formulate ethanol, a biofuel used as industrial feedstock. Released in a statement, the institute said the team, headed by Yugen Zhang, utilized N-heterocyclic carbenes, or NHCs, an organocatalyst in...

RIVERSIDE, Calif. "“ Aug. 18, 2005 "“ Chemists at the University of California, Riverside have synthesized a new class of carbenes "“ molecules that have unusual carbon atoms "“ that is expected to have wide applications in the pharmaceutical industry, ultimately resulting in a reduction in the price of drugs. Called cyclic alkyl amino carbenes or CAACs, the molecules attach themselves to metals, such as palladium, to form highly efficient catalysts that allow...
