Head‐to‐Tail Dimerization of N‐Heterocyclic Diazoolefins

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Andrzej Sienkiewicz, Tak Hin Wong, Zhaowen Dong, Paul Varava, Anastasia Gitlina, Wolfram Feuerstein

The head-to-tail dimerization of N-heterocyclic diazoolefins is described. The products of these formal (3+3) cycloaddition reactions are strongly reducing quinoidal tetrazines. Oxidation of the tetrazines occurs in a stepwise fashion, and we were able to ...

Synthesis and Reactivity of an Anionic Diazoolefin

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Bastiaan Kooij, Zhaowen Dong

Bent (hetero)allenes such as carbodicarbenes and carbodiphosphoranes can act as neutral C-donor ligands, and diverse applications in coordination chemistry have been reported. N-Heterocyclic diazoolefins are heterocumulenes, which can function in a similar ...

Multimetallic Uranium Nitride Cubane Clusters from Dinitrogen Cleavage

Rosario Scopelliti, Marinella Mazzanti, Farzaneh Fadaei Tirani, Ivica Zivkovic

Dinitrogen cleavage provides an attractive but poorly studied route to the assembly of multimetallic nitride clusters. Here, we show that the monoelectron reduction of the dinitrogen complex [{U(OC6H2-Bu-3(t)-2,4,6)(3)}(2)(mu-eta(2):eta(2)-N-2)], 1, allows ...

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 ...

A Route to Stabilize Uranium(II) and Uranium(I) Synthons in Multimetallic Complexes

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Dieuwertje Katelijn Modder

Herein, we report the redox reactivity of a multimetallic uranium complex supported by triphenylsiloxide (−OSiPh3) ligands, where we show that low valent synthons can be stabilized via an unprecedented mechanism involving intramolecular ligand migration. T ...

Uranium(IV) and Thorium(IV) Coordination Polymers Based on Tritopic Carboxylic Acids

Rosario Scopelliti, Marinella Mazzanti, Wendy Lee Queen, Farzaneh Fadaei Tirani, Anne-Sophie Chauvin, Till Marian Schertenleib, Aurélien René Willauer

Rigidtritopic linkers of different sizes were used to buildporous U-(IV) and Th-(IV) 3D frameworks. The charge of the polymerscould be tuned by reaction conditions such as the temperature, pH,solvent, ligand, or metal precursor, yielding a series of neutra ...

Multielectron Redox Chemistry of Uranium by Accessing the plus II Oxidation State and Enabling Reduction to a U(I) Synthon

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Anne-Sophie Chauvin

Thesynthesis of molecular uranium complexes in oxidation stateslower than +3 remains a challenge despite the interest for their multielectrontransfer reactivity and electronic structures. Herein, we report theone- and two-electron reduction of a U(III) com ...

Ruthenium(II)-Arene Complexes with Glycosylated NHC-Carbene Co-Ligands: Synthesis, Hydrolytic Behavior, and Binding to Biological Molecules

Paul Joseph Dyson, Rosario Scopelliti, Farzaneh Fadaei Tirani, Daniel Ortiz Trujillo, Mouna Hadiji

Ruthenium(II) complexes with a three-legged piano-stool structure based on an arene ring, an N-heterocyclic carbene (NHC)-carbene ligand with a peracetylated glucose moiety and two chlorides or one bidentate ligand, were prepared and characterized by spect ...

Dinitrogen cleavage by a dinuclear uranium(III) complex

Rosario Scopelliti, Marinella Mazzanti, Nadir Jori

Understanding the role of multimetallic cooperativity and of alkali ion-binding in the second coordination sphere is important for the design of complexes that can promote dinitrogen (N-2) cleavage and functionalization. Herein, we compare the reaction pro ...
