Carbon monoxide (CO) is one of the simplest and most fundamental molecules that has fascinated chemists for decades. Early-on, chemists have recognized and exploited its favorable properties as a key ...

We describe the reaction between the linear iron(I/II) silylamides [FeL2]0,– (L = N{Dipp}SiMe3) and aryl azides N3R with different steric demand (R = Ph, 2-Me-C6H4 (Tol), 2,4-Me2-C6H3 (Xyl), 2,6-iPr2-...

Low-valent cadmium compounds have remained largely unexplored as electron reservoirs, with no precedent for their use in reduction or bond activation chemistry. Here, we address this gap by integratin...

The reactivity of the kinetically stabilized stannylene (MesTer)2Sn (1) (MesTer = –C6H3-2,6-(2,4,6-Me3-C6H2)2) toward N2O is revisited, yielding the terminal tin(IV) hydroxide 2 via formal intramolecular C(sp3)–H activation of a putative terminal stannanone intermediate. By switching to Eind ligation (Eind = 1,1,3,3,5,5,7,7-octaethyl-s-hydrindacen-4-yl) at the tin center, the synthesis and characterization of the crystalline lithium salt (Eind)Li(THF)2 (3) is reported, serving as a straightforward precursor for the clean generation of the corresponding stannylene (Eind)2Sn (4). Compound 4 can be further cleanly converted into the heteroleptic Eind/halide stannylene (Eind)SnCl (6). Both 4 and 6 serve as suitable precursors for the synthesis of the heteroleptic s-hydrindacene-/amido-substituted stannylene (Eind)Sn{N(SiMe3)2} (5).

A series of cationic nido-clusters [E(η4-IDP)]+/2+ was prepared from the imidazolium-substituted diphosphate-diide (IPr)2C2P2 (IDP), including [1]+ (E = Ga) and [2b,c]2+ (E = Sn, Pb). As analogues of ...

The nickel-catalyzed Kumada–Tamao–Corriu cross-coupling reaction is widely used to form C–C bonds and receives continued interest due to the unique ability of nickel to activate challenging organic electrophiles containing C–F and C–O bonds. Recent studies on the nickel-catalyzed cross-coupling of Ar–F and Ar–OMe electrophiles with organolithium nucleophiles have unveiled the key involvement of highly reactive anionic nickelates, in which Li and Ni cooperatively promote the activation of these substrates. However, the possible formation of related heterobimetallic intermediates when employing organomagnesium nucleophiles as cross-coupling partners still remains widely underexplored. Filling this gap in the knowledge, we use air-stable Ni-tris(olefin), Ni(4-Me-stb)3 (where stb = stilbene), as a Ni(0) precursor to systematically investigate its reactivity toward several organomagnesium and organolithium reagents, which has allowed for the structural and spectroscopic characterization of a new family of nickelate complexes. Their possible implications and the influence of their constitution and speciation on the outcome of Kumada–Tamao–Corriu cross-couplings are also investigated through a series of stoichiometric and catalytic reactions, which have uncovered a dramatic solvent effect, hinting at the formation of contacted ion pair species as key to maximizing Mg (or Li)/Ni(0) cooperativity.

Molecular chemistry of aluminum most commonly involves AlIII ions due to their noble gas electronic configurations. In contrast, the chemistry of AlII ions is underexplored and may contain undiscovere...

In this work, we disclose the synthesis and characterization of non-acid/base-stabilized anionic oxoboranes [MesTer2BO][K(L)] (MesTer = –C6H3-2,6-(2,4,6-Me3-C6H2)2, L = [2.2.2]-cryptand or 18-crown-6)...
