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

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

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 ...

Divergent Asymmetric Synthesis of Polycyclic Compounds via Vinyl Triazenes

Rosario Scopelliti, Kay Severin, Nicolai Cramer, Gregor Kiefer, Abdusalom Suleymanov, David Kossler, Florian Gérald Abela

Vinyl triazenes were obtained by enantioselective [2+2] cycloaddition reactions of bicyclic alkenes with 1-alkynyl triazenes in the presence of a RuII catalyst with a chiral cyclopentadienyl ligand. These triazenes serve as unique vinyl cation surrogates. ...

Ethynyl Benziodoxolones for the Direct Alkynylation of Heterocycles: Structural Requirement, Improved Procedure for Pyrroles, and Insights into the Mechanism

Rosario Scopelliti, Jérôme Waser, Jonathan Brand

This report describes a full study of the gold-catalyzed direct alkynylation of indoles, pyrroles, and thiophenes using alkynyl hypervalent iodine reagents, especially the study of the structural requirements of alkynyl benziodoxolones for an efficient ace ...

Why are (NN2)Ni pincer complexes active for alkyl-alkyl coupling: ß-H elimination is kinetically accessible but thermodynamically uphill

Rosario Scopelliti, Xile Hu, Anne-Clémence Corminboeuf, Oleg Vechorkin, Jan Breitenfeld

Isomerization and olefin exchange experiments show that β-H elimination is kinetically viable but thermodynamically unfavorable in [(MeNN2)Ni-alkyl] complexes. The intermediacy of Ni-hydride species was corroborated by a trapping experiment. The alkyl comp ...
