For the first time, a transient singlet carbene has been trapped--and stabilized--for days inside the cavity of a cage molecule at ambient temperature, according to chemists at Rutgers University. For ...

With a chemical "trick," scientists have succeeded in isolating a stable gold carbene complex. Chemists have now created the basis for directly examining the otherwise unstable gold-carbon double bond ...

Photosensitizers absorb sunlight and pass that energy along to generate electricity or drive chemical reactions. Scientists watched what happened when light hit an inexpensive photosensitizer, iron ...

The discovery two decades ago of metal-free stable carbenes, especially imidazol-2-ylidenes [N-heterocyclic carbenes (NHCs)], has led to numerous breakthroughs in organic and organometallic catalysis.

Osaka, Japan – While we appear to live in a world of plenty, behind the scenes, sourcing sufficient amounts of key ingredients can be challenging. For example, the synthesis of certain antibiotics, ...

A new family of cyclic carbene ligands has been synthesized, expanding the arsenal of these popular ligands and opening a door to homogeneous catalysis of a broader range of chemical reactions. "The ...

Aryl halides*1) with a benzene ring directly bonded to a halogen atom are readily available and chemically stable, so they are used as a source of benzene rings in organic synthesis. For example, a ...

A team of chemists from the University of California, Riverside (UCR, Riverside, CA) has discovered a new carbene-based catalyst that makes chemical reactions faster and more economical. Unlike most ...
