Dinuclear clathrochelate complexes with pendent cyano groups as metalloligands

Kay Severin, Rosario Scopelliti, Euro Solari, Bálint Náfrádi, Philip Pattison, Henrik Moodysson Rønnow, Ivica Zivkovic, Mathieu Jérémie Marmier, Giacomo Cecot, José Luis Bila

Dinuclear clathrochelate complexes with two, three, four, or five cyano groups in the ligand periphery were prepared following two distinct synthetic strategies: (a) zinc(II)- or cobalt(II)-templated polycondensation reactions of CN-functionalized arylboro ...

Large heterometallic coordination cages with gyrobifastigium-like geometry

Kay Severin, Rosario Scopelliti, Euro Solari, Stéphanie Prior, Bassam Alameddine, Farzaneh Fadaei Tirani, Giacomo Cecot

Large coordination cages with unusual gyrobifastigium-like geometry were obtained by combining cis-blocked PtII or PdII complexes with clathrochelate-based metalloligands ...

Large, heterometallic coordination cages based on ditopic metallo-ligands with 3-pyridyl donor groups

Kay Severin, Rosario Scopelliti, Euro Solari, Philip Pattison, Matthew David Wise

Ditopic N-donor ligands with terminal 4-pyridyl groups are omnipresent in coordination-based self-assembly. The utilization of ligands with 3-pyridyl donor groups is significantly less common, because the intrinsic conformational flexibility of these ligan ...

Synthesis of Azoimidazolium Dyes with Nitrous Oxide

Kay Severin, Rosario Scopelliti, Euro Solari, Alexander Tskhovrebov

A new method for the synthesis of industrially important azoimidazolium dyes is presented. The procedure is based on a reagent which is rarely used in the context of synthetic organic chemistry: nitrous oxide (“laughing gas”). N2O is first coupled to N-het ...

Reactions of Grignard Reagents with Nitrous Oxide

Kay Severin, Rosario Scopelliti, Euro Solari, Alexander Tskhovrebov

The chemical activation of nitrous oxide (N2O) can be achieved by organocalcium, organosodium, and organolithium compounds. Grignard reagents, on the other hand, are believed to be inert. We demonstrate that this generalization is not correct. Some aliphat ...

Contributions to the Chemistry of the Cyclopentadienyl Complex [Cp^RuCl2](2) ("Cp-roof" = eta(5)-1-Methoxy-2,4-tert-butyl-3-neopentylcyclopentadienyl)

Kay Severin, Rosario Scopelliti, Euro Solari, Julie Risse, Barnali Dutta

The dimeric ruthenium complex Cp^RuCl2 is easily accessible in a one-pot reaction from RuCl3(solv)(n) and tert-butylacetylene. It features sterically very demanding "Cp-roof" ligands (Cp^ = eta(5)-1-methoxy-2,4-tert-butyl-3-neopentylcyclopentadienyl), ...

Insertion of Zerovalent Nickel into the N–N Bond of N-Heterocyclic-Carbene-Activated N2O

Kay Severin, Rosario Scopelliti, Euro Solari, Alexander Tskhovrebov

Metal-mediated cleavage of the N–N bond is a rarely observed phenomenon in the chemistry of nitrous oxide (N2O). We demonstrate that, upon activation of N2O with N-heterocyclic carbenes, zerovalent nickel is able to insert into the N–N bond to give nitrosy ...

Adducts of Nitrous Oxide and N-Heterocyclic Carbenes: Syntheses, Structures, and Reactivity

Kay Severin, Rosario Scopelliti, Euro Solari, Basile Vuichoud, Alexander Tskhovrebov

N-Heterocyclic carbenes (NHCs) react at ambient conditions with nitrous oxide to give covalent adducts. In the crystal, all compounds show a bent N2O group connected via the N-atom to the former carbene carbon atom. Most adducts are stable at room temperat ...

Activation of Nitrous Oxide by Dinuclear Ruthenium Complexes

Kay Severin, Rosario Scopelliti, Euro Solari, Alexander Tskhovrebov

The dinuclear Ru(II) complexes (arene)Ru(μ-Cl)3RuCl(C2H4)(PCy3) (arene = p-cymene or 1,3,5-C6H3iPr3) react with N2O under mild conditions to give OPCy3 and the trinuclear complexes (arene)Ru(μ-Cl)3Ru(μ-Cl)3Ru(arene). The N-heterocyclic carbene complex (p-c ...

Ruthenium-Catalyzed Sequential Enyne Cross-Metathesis/ATRA Reactions

Kay Severin, Euro Solari, Jesus Ruiz, Gregor Kiefer

Sequential enyne cross-metathesis reactions of arylalkynes with ethylene followed by atom transfer radical addition (ATRA) with ethyl dichloroacetate or dichloroacetonitrile provide 1,5-dichloropent-2-ene derivatives. The second-generation Grubbs alkyliden ...

RhCl3-Mediated Coupling Reactions of tert-Butyl Acetylene

Kay Severin, Rosario Scopelliti, Euro Solari, Barnali Dutta, Gregor Kiefer

RhCl3 is shown to mediate unusual coupling reactions of tert-butyl acetylene. When RhCl3(H2O)n was heated with four equivalents of tert-butyl acetylene in methanol, the dinuclear complex [{Rh(μ-Cl)(CH2tBu)(tBuC=CHCOCH2tBu)}2] (2) was isolated. A larger exc ...

Sequential N–O and N–N Bond Cleavage of N-Heterocyclic Carbene-Activated Nitrous Oxide with a Vanadium Complex

Kay Severin, Rosario Scopelliti, Euro Solari, Matthew Wodrich, Alexander Tskhovrebov

Chemically induced bond cleavage of nitrous oxide typically proceeds by rupture of the N–O bond with concomitant O-atom transfer and liberation of dinitrogen. On a few occasions, N–N bond scission has been observed instead. We report a reaction sequence in ...

Covalent Capture of Nitrous Oxide by N-Heterocyclic Carbenes

Kay Severin, Rosario Scopelliti, Euro Solari, Matthew Wodrich, Alexander Tskhovrebov

A good catch: N-heterocyclic carbenes (NHCs) form stable adducts with nitrous oxide (N2O) under mild reaction conditions. The adducts display unique reactivity as evidenced by an alkylation reaction which leads to a rupture of the NN bond. ...

Room-temperature combinatorial screening of cyclometallated iridium(III) complexes for a step towards molecular control of colour purity

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Euro Solari, Il Jung

A library of emission spectra of 90 bis-cyclometallated iridium complexes has been obtained using a simple combinatorial approach performed at room temperature. Trends in emission maxima are rationalized using Hammett parameters and invoking inter ligand e ...

Reactions of Alkynes with [RuCl(cyclopentadienyl)] Complexes: The Important First Steps

Kay Severin, Rosario Scopelliti, Euro Solari, Ursula Röthlisberger, Basile Curchod, Barnali Dutta, Pablo Campomanes Ramos

Cyclopentadienyl-ruthenium half-sandwich complexes with 2-bound alkyne ligands have been suggested as catalytic intermediates in the early stages of Ru-catalyzed reactions with alkynes. We show that electronically unsaturated complexes of the formula [RuCl ...

Multifaceted Chemistry of [(Cymene)RuCl2]2 and PCy3

Kay Severin, Rosario Scopelliti, Euro Solari, Sébastien Gauthier

The reaction of (cymene)RuCl2 (1) with PCY3 was investigated using different stoichiometries and reaction conditions. Whereas a mixture of complex 1 and 2 equiv of PCy3 in methanol gave the known adduct [(cymene)Rucl(2)(PCy3)] (3) along with the phosp ...
