A transition metal carbene complex is an organometallic compound featuring a divalent carbon ligand, itself also called a carbene. Carbene complexes have been synthesized from most transition metals and f-block metals, using many different synthetic routes such as nucleophilic addition and alpha-hydrogen abstraction. The term carbene ligand is a formalism since many are not directly derived from carbenes and most are much less reactive than lone carbenes. Described often as =CR2, carbene ligands are intermediate between alkyls (−CR3) and carbynes (≡CR). Many different carbene-based reagents such as Tebbe's reagent are used in synthesis. They also feature in catalytic reactions, especially alkene metathesis, and are of value in both industrial heterogeneous and in homogeneous catalysis for laboratory- and industrial-scale preparation of fine chemicals.
Friedrich Asinger was an Austrian chemist and professor for Technical Chemistry. He is well known for his development of a multi-component reaction, the Asinger reaction for the synthesis of 3-thiazolines.
A frustrated Lewis pair (FLP) is a compound or mixture containing a Lewis acid and a Lewis base that, because of steric hindrance, cannot combine to form a classical adduct. Many kinds of FLPs have been devised, and many simple substrates exhibit activation.
Stefan Hecht is a German chemist.
Alexander C. Filippou has been a Professor of Inorganic Chemistry at the Rheinische-Friedrich-Wilhelms-University Bonn since 2005.
Within the area of organocatalysis, (thio)urea organocatalysis describes the use of ureas and thioureas to accelerate and stereochemically alter organic transformations. The effects arise through hydrogen-bonding interactions between the substrate and the (thio)urea. Unlike classical catalysts, these organocatalysts interact by non-covalent interactions, especially hydrogen bonding. The scope of these small-molecule H-bond donors termed (thio)urea organocatalysis covers both non-stereoselective and stereoselective reactions.
Didier Astruc carried out his studies in chemistry in Rennes. After a Ph. D. with professor R. Dabard in organometallic chemistry, he did post-doctoral studies with professor R. R. Schrock at the Massachusetts Institute of Technology Cambridge, Massachusetts, in the U.S. and later a sabbatical year with professor K. P. C. Vollhardt at the University of California at Berkeley. He became a CNRS Director of research in Rennes, then in 1983 full Professor of Chemistry at the University Bordeaux 1. He is known for his work on electron-reservoir complexes and dendritic molecular batteries, catalytic processes using nanoreactors and molecular recognition using gold nanoparticles and metallodendrimers.
Ulrich "Uli" Kortz is a German chemist and professor, working in the area of synthetic polyoxometalate chemistry.
Heribert Offermanns is a German chemist and former member of the board of the Degussa AG.
Douglas Wade Stephan is professor of Chemistry at the University of Toronto, a post he has held since 2008.
Maki Kawai is a Japanese chemist who developed spatially selective single-molecule spectroscopy. In 2018, she became the first woman to become president of the Chemical Society of Japan.
Corinna S. Schindler is a Professor of Chemistry at the University of Michigan. She develops catalytic reactions with environmentally benign metals such as iron, towards the synthesis of biologically active small molecules. For her research in the development of new catalysts, Schindler has been honored with several early-career researcher awards including the David and Lucile Packard Foundation Fellowship in 2016, the Alfred P. Sloan Fellowship in 2017, and being named a member of the C&EN Talented 12 in 2017. Schindler has served on the Editorial Board of Organic and Bimolecular Chemistry since 2018.
