Here we report the catalytic activation of simple saturated ester β-carbons as nucleophiles (β-carbon activation) using N-heterocyclic carbene organocatalysts. The catalytically generated ...

Based on the comparisons, they found that plutonium’s bonding to the alkylidene and N-heterocyclic carbene ligands was more covalent than predicted, hinting that f-block elements’ behavior isn ...

For example, the large-scale production of many ... at Heidelberg University have succeeded in isolating a stable gold carbene complex. Chemist Prof. Dr. Bernd F. Straub and his team are the ...

Synthesis and determination of 7′.(A) Synthesis of carbenoid 6′ and carbene 7′.The reaction is clean and quantitative when LiHMDS is used as a base and pure THF as the solvent. (B) Three ...

Highly reactive gold carbene complex shines in emerald green Date: July 8, 2014 Source: Heidelberg, Universität Summary: With a chemical "trick," scientists have succeeded in isolating a stable ...

Through some other chemical tweaks on top of the protective structure, the carbene could be kept stable ... It's another example of the serendipitous scientific discoveries that can sometimes ...

All this is thanks to the stabilization of a molecule known as a carbene, which is a specific type of water-reactive atom with six valence electrons. This is also important to understand the ...
