A Highly Reduced Magnesium Dicobalt Complex for the Hydrogenation of Tri- and Tetra-Substituted Alkenes The reaction of [K(thf)0.33][Co(η4-cod)2] (E; cod = 1,5-cyclooctadiene) with 0.5 equiv of MgCl2 led to the isolation of the magnesium dicobalt complex Mg[Co(η4-cod)2]2 (1). Complex 1 forms a tight ionic complex in the solid state and in toluene solution due to electrostatic interactions between the Mg2+ cation and the [Co(η4-cod)2]− anions. The complex is a successful precatalyst for the hydrogenation of sterically challenging tri- and tetra-substituted alkenes, surpassing the catalytic capabilities of related alkali metal and β-diketiminate magnesium complexes.

Counterintuitive Photochemistry of an Isolated Acridinyl Radical: ConPET via Preassembly Despite a Long-Lived Excited State Photoredox chemistry has seen a dramatic rise in popularity in recent years, but mechanistic understanding has persistently lagged behind reaction development itself. This is particularly true for the...

New preprint on ChemRxiv!
Our latest exploration of conPET/e-PRC #photoredox highlights preassembly and "anti-Kasha" reactivity, even in a system with a long ES lifetime.
Thanks to all involved, including collaborators at HUN-REN and Uni of Warwick.

Transient Triplet Metallopnictinidenes M–Pn (M = PdII, PtII; Pn = P, As, Sb): Characterization and Dimerization Nitrenes (R–N) have been subject to a large body of experimental and theoretical studies. The fundamental reactivity of this important class of transient intermediates has been attributed to their electronic structures, particularly the accessibility of triplet vs singlet states. In contrast, electronic structure trends along the heavier pnictinidene analogues (R–Pn; Pn = P–Bi) are much less systematically explored. We here report the synthesis of a series of metallodipnictenes, {M–Pn═Pn–M} (M = PdII, PtII; Pn = P, As, Sb, Bi) and the characterization of the transient metallopnictinidene intermediates, {M–Pn} for Pn = P, As, Sb. Structural, spectroscopic, and computational analysis revealed spin triplet ground states for the metallopnictinidenes with characteristic electronic structure trends along the series. In comparison to the nitrene, the heavier pnictinidenes exhibit lower-lying ground state SOMOs and singlet excited states, thus suggesting increased electrophilic reactivity. Furthermore, the splitting of the triplet magnetic microstates is beyond the phosphinidenes {M–P} dominated by heavy pnictogen atom induced spin–orbit coupling.

Our paper on triplet pnictinidenes (P, As, Sb) with transition metal substituents is out; congrats to Marc, Nils, Tarek and Rich and thanks to all that have contributed to get a comprehensive electronic structure picture @haenisch-group.bsky.social
