Synthesis, isolation and application of a sila-ketenyl anion

Rosario Scopelliti, Shiori Fujimori

Ynolates or ketenyl anions, [RCCO]-, are negatively charged reactive intermediates, which can be generated in situ and used for divergent chemical transformations. Ynolates can react either at the oxygen or carbon centres or across the C-C triple bond, mak ...

Copper Complexes with Diazoolefin Ligands and their Photochemical Conversion into Alkenylidene Complexes

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Bastiaan Kooij, Paul Varava

Homometallic copper complexes with alkenylidene ligands are discussed as intermediates in catalysis but the isolation of such complexes has remained elusive. Herein, we report the structural characterization of copper complexes with bridging and terminal a ...

Electro- and photochemical H-2 generation by Co(ii) polypyridyl-based catalysts bearing ortho-substituted pyridines

Rosario Scopelliti, Euro Solari, Albert Ruggi, Vincent Artero, Fiorella Lucarini

Cobalt(II) complexes featuring hexadentate amino-pyridyl ligands have been recently discovered as highly active catalysts for the Hydrogen Evolution Reaction (HER), whose high performance arises from the possibility of assisting proton transfer processes v ...

Retarding solid-state reactions enable efficient and stable all-inorganic perovskite solar cells and modules

Mohammad Khaja Nazeeruddin, Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Farzaneh Fadaei Tirani, Yong Ding, Bin Ding, Yen-Cheng Liu, Hiroyuki Kanda, Olga Syzgantseva

All-inorganic CsPbI3 perovskite solar cells (PSCs) with efficiencies exceeding 20% are ideal candidates for appli-cation in large-scale tandem solar cells. However, there are still two major obstacles hindering their scale-up: (i) the inhomogeneous solid-s ...

Heterometallic uranium/molybdenum nitride synthesis via partial N-atom transfer

Rosario Scopelliti, Marinella Mazzanti, Luciano Barluzzi, Nadir Jori

The reaction of a terminal Mo(II) nitride with a U(III) complex yields an heterodimetallic U-Mo nitride which is the first example of a transition metal-capped uranium nitride. The nitride is triply bonded to U(V) and singly bonded to Mo(0) and supports a ...

Vanadium complexes with N-heterocyclic vinylidene ligands

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Laura Piveteau, Bastiaan Kooij, Zhaowen Dong, Paul Varava

The preparation and the structural characterization of vanadium complexes with terminal and bridging N-heterocyclic vinylidene ligands is reported. The synthesis of the complexes was enabled by utilization of diazoolefins as ligand precursors. Structural d ...

Fluorinated Tetraarylethenes: Universal Tags for the Synthesis of Solid State Luminogens

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Euro Solari, Albert Ruggi, Abdusalom Suleymanov, Thibault Jacques Marie Damiens Vanrapenbusch, Barbara Maja Kraus

The aggregation-induced emission properties of tetraarylethenes (TAEs) have led to numerous applications in chemistry, biology, and materials science. Herein, we describe two fluorinated tetraarylethenes, which can be employed as universal tags for the syn ...

A Mesoionic Diselenolene Anion and the Corresponding Radical Dianion

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Andrzej Sienkiewicz, Cesare Berton, Abdusalom Suleymanov, Zhaowen Dong

Dichalcogenolenes are archetypal redox non-innocent ligands with numerous applications. Herein, we describe a diselenolene ligand with fundamentally different electronic properties. By selenation of a C2-protected imidazolium salt, we have prepared a mesoi ...

LiBF4‐Induced Rearrangement and Desymmetrization of a Palladium‐Ligand Assembly

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Sylvain Alexandre Marie Sudan

Thirteen palladium-ligand assemblies with different structures and topologies were investigated for the ability to bind lithium ions. In one case, the addition of LiBF4 resulted in a profound structural rearrangement, converting a dincluclear [Pd2L4]2 comp ...

Assembling diuranium complexes in different states of charge with a bridging redox-active ligand

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

Radical-bridged diuranium complexes are desirable for their potential high exchange coupling and single molecule magnet (SMM) behavior, but remain rare. Here we report for the first time radical-bridged diuranium(IV) and diuranium(III) complexes. Reaction ...
