Figure 1: Spectroscopic evidence for the accumulation of a thiamin-based carbene in pyruvate oxidase. Figure 3: Geometric properties of the carbene in pyruvate oxidase. Our study demonstrates that ...

Using crystallography and spectroscopy, they verified the structures and compared their bond lengths and reactivity ... the alkylidene and N-heterocyclic carbene ligands was more covalent than ...

Chemists have now created the basis for directly examining the otherwise unstable gold-carbon double bond. They explain that highly reactive gold carbene molecules play an important role in ...
