Dihydrogen complexation, a phenomenon with robust precedent in the transition metal series, is spectroscopically detected for uranium(III) complex and thereby extended first time to 5f series. The vacant coordination site low valence of (C5H4SiMe3)3U prove be key reversible formation (C5H4SiMe3)3U–H2 (complex 1), paramagnetism f3 center facilitates detection 1 by NMR spectroscopy. Density functional theory calculations reveal that delocalization electron density from onto side-on dihydrogen...
We report the synthesis of actinide–osmium polyhydrides and demonstrate their ability to promote photo-induced intra- intermolecular C–H activation.
While carbene complexes of uranium have been known for over a decade, there are no reported examples between an actinide and "heavy carbene." Herein, we report the syntheses structures first uranium-heavy tetrylene complexes: (CpSiMe3 )3 U-Si[PhC(NR)2 ]R' (R=tBu, R'=NMe2 1; R=iPr, R'=PhC(NiPr)2 2). Complex 1 features kinetically robust uranium-silicon bonding interaction, while bond in 2 is easily disrupted thermally or by competing ligands solution. Calculations reveal polarized σ bonds,...
Salt metathesis reactions between a low-valent rhenium(<sc>i</sc>) complex and series of amidinate-supported tetrylenes led to rhenium metallotetrylenes with varying extents Re–E multiple bonding.
While synthesizing a series of rhenium-lanthanide triple inverse sandwich complexes, we unexpectedly uncovered evidence for rare examples end-on lanthanide dinitrogen coordination certain heavy elements as well uranium. We begin our report with the synthesis and characterization trirhenium complexes early lanthanides, Ln[(μ-η
The electronic organization of Frustrated Lewis Pairs (FLPs) allows them to activate strong bonds in mechanisms that are usually free redox events at the acidic site. unique 6d/5f manifold uranium could serve as an interesting FLP acceptor site, but date FLP-like catalysis with actinide ions is unknown. In this paper, catalytic, hydrogenation reactivity trivalent complexes explored presence base-stabilized silylenes. Comparison isoelectronic, isostructural lanthanide and thorium lends...
