Cornell advance could be a first step to low-energy industrial chemical production. A fundamental laboratory advance has made it possible to break, at room temperature and pressure, two of the strongest types of chemical bonds in order to make common

industrial compounds. In doing so, researchers at Cornell University have taken an important first step toward less-energy-intensive processes for making nitrogen-containing organic compounds. "The nitrogen-carbon bond is the backbone of almost all top-selling pharmaceuticals," [Less]

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. Chemists had assumed that aNHCs cannot exist freely, which made them impossible to make.
Now UC Riverside's Guy Bertrand, a distinguished professor of chemistry, and colleagues have challenged that assumption by successfully creating aNHCs that are metal-free and can be used to make any desired complex. [Less]
