Merging the Reactivity of (Pseudo)cyclic Hypervalent Iodine Reagents and Carbenes or Carbenoids

Jérôme Waser, Nieves Pilar Ramirez Hernandez

In this short review, we present applications merging the reactivity of cyclic hypervalent iodine reagents with carbenes and carbenoids developed in the last decade. The use of more stable cyclic hypervalent iodine reagents has led to major advances in thi ...

One-pot synthesis of functionalized bis(trifluoromethylated)benziodoxoles from iodine(i) precursors

Jérôme Waser, Xingyu Liu, Nieves Pilar Ramirez Hernandez, Tobias Michael Milzarek

Bis(trifluoromethylated)benziodoxoles (Bx) are broadly used cyclic hypervalent iodine reagents due to their stability and unique chemical properties. However, current methods to access them require several steps and long reaction times, making their synthe ...

X-Ray and NMR Structural Data of Ethynylbenziodoxolones (EBXs) Reagents and Their Analogues

Rosario Scopelliti, Jérôme Waser, Farzaneh Fadaei Tirani, Matthew Wodrich, Stefano Nicolai, Durga Prasada Rao Hari, Eliott Hugo Joran Le Du, Nieves Pilar Ramirez Hernandez

First synthesized in 1991, EthynylBenziodoXolones (EBXs) - cyclic hypervalent iodine reagents derived from 2-iodobenzoic acid - are now among the most versatile electrophilic alkynylation reagents. Due to their cyclic structure, these reagents exhibit enha ...

Copper (I)‐BOX Catalyzed Asymmetric 3‐Component Reaction for the Synthesis of Trifluoromethylated Propargylic Ethers and Anilines**

Jérôme Waser, Nieves Pilar Ramirez Hernandez

An asymmetric 3-component reaction between EthynylBenziodoXoles (EBXs), 2,2,2-trifluorodiazoethane and nucleophiles catalyzed by a CuI-BOX (Bisoxazoline) catalyst is described. This protocol gives access to chiral trifluoromethylated propargyl ethers and a ...

Cu(I)-Catalyzed gem-Aminoalkynylation of Diazo Compounds: Synthesis of Fluorinated Propargylic Amines

Jérôme Waser, Guillaume Dominique Pisella, Nieves Pilar Ramirez Hernandez

The gem-aminoalkynylation of fluorinated diazo compounds catalyzed by a simple Cu(I) salt is described. This three-component reaction allows the synthesis of propargylic amines with broad functional group tolerance. Both electron-rich and electron-poor ani ...
