Reactivity of Diaryl Bismuth Cations toward a Platinum(0) Complex: Oxidative Aryl Transfer Reactions of three aryl-substituted bismuth cations, [BiPh2(SbF6)], [BiMes2(SbF6)], and [BiDipp2(SbF6)], with the Pt0 complex Pt(PCy3)2 have been investigated (Mes = 2,4,6-trimethyl-phenyl; Dipp = 2,6-di-iso-propyl-phenyl; Cy = cyclohexyl). Unexpectedly, and in contrast with the reactivity of the recently reported methyl analogue [BiMe2(SbF6)], the formation of isolable metal-only Lewis pairs [(Cy3P)2Pt→BiAr2(SbF6)] is not observed (Ar = aryl). Instead, an unprecedented bismuth-to-platinum oxidative aryl transfer is witnessed to give the PtII complexes [PtAr(PCy3)2(SbF6)], along with the suggested bismuthinidene intermediates BiAr. Attempts to trap these fleeting intermediates with an ortho-quinone led to a PtII semiquinone radical complex.

#Bismuth meets platinum (#1): diaryl bismuth cations undergo oxidative aryl transfer to Pt(0)! Attempts to trap the low-valent Bi intermediate yielded a Pt radical complex. Now out in the p-block special issue of #Organometallics, @pubs.acs.org: pubs.acs.org/doi/10.1021/... Congrats to the team!

Nonlinear Pathway for Remote Metal–Metal Communication in Heterobimetallic Complexes Enabled by Mixed NHC Ligands: Influence of Metal Coordination Modes This work presents unique examples of two heterobimetallic complexes 4 and 5 that share the same overall molecular composition but display distinctly different electrochemical properties. These complexes were synthesized in high yields from an unsymmetrical bis-triazolium ligand precursor with a phenyl spacer (1) featuring differently acidic triazolium moieties via sequential regioselective metalation. Despite the potential for doubly orthometalated systems, these complexes demonstrate unusual binding modes on a single ligand platform: One is orthometalated with the normal NHC (1,2,4-TzNHC) moiety, while at the same time, the other metal is nonorthometalated at the unusual C4 position of the abnormal NHC (1,2,3-TzNHC) motif. This molecular design significantly enhances the electronic properties of the complexes, facilitating the intramolecular metal-to-metal electronic communication between the RuII and RhIII centers through the bridging NHC ligand, although these metal ions are separated by ∼9 Å. Detailed spectroelectrochemical investigations reveal that out of the two constitutional isomers 4 and 5, complex 5, which features a cyclometalated RuII moiety, exhibits superior redox activity and enhanced UV–vis–NIR absorption compared to complex 4, also supported by DFT studies. This study provides a pioneering example of how the binding sites and coordination modes of metal ions influence the electrochemical behavior of NHC-coordinated heterobimetallic complexes.

Revisiting CNC6F5: The Quest for Isocyanide Ligands with Strong π-Acceptor Properties Evaluated by Energy Decomposition Analysis While perfluorinated isocyanide ligands such as CNCF3 and CNC6F5 have been known for decades, their use by organometallic chemists has been limited primarily due to the challenges associated with their cumbersome synthesis. In this study, we present an improved synthetic route to [Cr(CO)5(CNC6F5)] and present its structural characterization. For a set of isocyanide ligands (CNC6H5, p-CNC6H4F, CNCH3) and their perfluorinated counterparts (CNC6F5, CNCF3), Gibbs energies of complexation have been calculated with regard to a series of isoelectronic metal fragments [V(CO)5]−, [Cr(CO)5], [Mn(CO)5]+, and [Fe(CO)5]2+. Furthermore, the σ-donor and π-acceptor properties of these isocyanide ligands in the resulting complexes were analyzed using the EDA-NOCV method. For completeness, we have also included ligands such as CO, CNH, and N2 into the analysis. While only minor differences in complexation energies are observed for the Cr(CO)5 fragment, more pronounced effects have been observed for the charged complexes. Interestingly, perfluorinated isocyanide ligands show in all cases higher complexation energies than the carbonyl ligands, indicating their strong binding to metal centers. Their pronounced σ-donor and π-acceptor abilities reveal their potential suitability to stabilize metal centers in both positive and negative oxidation states.

New paper out in ACS Omega:
We compare the σ-donor and π-acceptor properties of fluorinated isocyanide complexes with their non-fluorinated analogues using the EDA-NOCV method.

Structural and Reactivity Implications of Homo- and Heterobimetallic Co(II) Amides Prepared via Trans(amination) Reactions Cobalt(II) bis(amides)are widely applied in catalysis and material science. Typically, they are prepared via salt metathesis, by reacting a lithium amide with a CoX2 (X = Cl, Br) salt, requiring, in many cases, the use of low temperatures and other solvents. This work introduces an alternative approach, assessing the reactivity of classical Co(II) amide [Co(HMDS)2] (1) [HMDS = N(SiMe3)2] and heterobimetallic [NaCo(HMDS)3] (6) as precursors for trans(amination) reactions with DPA(H) (2,2′-dipyridylamine), N-methylaniline, and piperidine. When reacted with the most acidic amine DPA(H), both showed polybasic behavior with excellent stoichiometric control according to the equivalents of DPA(H) employed. Reactions with and piperidine led to an incomplete exchange of the HMDS groups present in 1, even when an excess of the relevant amine is employed. Contrastingly, when assessing the reactivity of sodium cobaltate 6 with these amines, kinetic activation of two (or three) of its HMDS-arms was observed, forming new heterobimetallic species which in all cases proved unstable, undergoing dissociation into their monometallic components or a ligand redistribution process. The catalytic potential of the novel Co(II) complexes was investigated for the hydrosilylation of acetophenone, finding that faster reaction rates and higher chemoselectivities were achieved when using the heterobimetallic Na/Co systems.
