Enantio- and diastereoselective construction of vicinal C(sp(3)) centres via nickel-catalysed hydroalkylation of alkenes

Xile Hu, Srikrishna Bera, Chao Fan

In drug discovery, the proportion of aliphatic carbons (C(sp(3))) and the presence of chiral carbons in organic molecules are positively correlated to their chance of clinical success. Although methods exist for the synthesis of chiral C(sp(3))-rich molecu ...

Mapping Catalyst‐Solvent Interplay in Competing Carboamination/Cyclopropanation Reactions

Anne-Clémence Corminboeuf, Nicolai Cramer, Matthew Wodrich, Simone Gallarati, Lukasz Piotr Wozniak, Miyeon Chang

Group 9 metals, in particular Rh III complexes with cyclopentadienyl ligands, are competent C–H activation catalysts. Recently, a Cp*Rh III catalyzed reaction of alkenes with N -enoxyphthalimides showed divergent outcome based on the solvent, with carboami ...

Chlorination of Phenols Revisited: Unexpected Formation of α,β-Unsaturated C4-Dicarbonyl Ring Cleavage Products

Urs von Gunten

Despite decades of research on the fate of phenolic compounds when water is disinfected with hypochlorous acid (HOCl), there is still considerable uncertainty regarding the formation mechanisms and identity of ring cleavage products, especially at higher c ...

Stereoselective synthesis of alkenes via base-metal-catalyzed addition reactions to alkynes and activation of hydrogen peroxide and carbon dioxide by iron complexes

Fedor Zhurkin

Alkene functionality can be found in the majority of natural products, drugs, catalysts and organic materials. Therefore, methods of C-C double bond formation constitute a cornerstone of organic synthesis. Selective formation of either (Z)- or (E)-isomer i ...

Mild synthesis of mercaptonitriles from vinyl nitriles and their cyclization reactions

Frank Nüesch, Antonia Neels

Thiol-ene addition of thioacetic acid A is widely used in the synthesis of thiols from vinyl precursors, but so far has not been conducted on non-conjugated vinyl nitriles. The challenge when vinyl nitriles are used is to selectively conduct the thiol-ene ...

Chiral Cyclopentadienyl Ligands Enable a Rhodium(III)-Catalyzed Enantioselective Access to Hydroxychromanes and Phthalides

Nicolai Cramer, Baihua Ye

The demand for efficient chiral cyclopentadienyl ligands (Cp-x) has increased significantly in recent years, partly because Cp*Rh(III) species have been developed as powerful catalysts for directed C-H functionalization reactions. However, a lack of suitab ...

Electrophilic alkynylation: the dark side of acetylene chemistry

Jérôme Waser, Jonathan Brand

In addition to the well-established nucleophilic alkynylation, the use of electrophilic alkynes can expand tremendously the scope of acetylene transfer reactions. The use of metal catalysis has recently led to a rebirth of this research area. Halogenoalkyn ...

Buttressing effects responsible for the meta-deprotonation of trialkylsilyl-substituted haloarenes by organometallic reagents : an unprecedented phenomenon

Christophe Heiss

(2,6-Dichlorophenyl)trimethyl- and triethylsilane exhibit untypical reactivity patterns toward strong bases: when treated at -100 °C with lithium 2,2,6,6-tetramethylpiperidide two, with sec- or tert-butyllithium even three organometallic intermediates are ...
