Abstract

We report the synthesis of two metal bis(amidophosphine selenide) complexes, ML₂ (M = Fe, Co; L = SePPh₂N⁽⁻⁾Tol), and investigate their reactivity toward ligand binding and oxidation with oxygen atom transfer reagents, pyridine-N-oxide and mesityl nitrile oxide. The oxidative strength of the reagent dictates the nature of the reactivity: either the ligand is oxidized, leading to the formation of a bimetallic mixed-ligand complex [MLL′]_n, (L′ = OPPh₂N⁽⁻⁾Tol), or the metal center is oxidized, resulting in a bimetallic μ-oxo complex [FeL₂]₂(μ₂-O). This study defines a chemical space in which amidophosphine selenide ligands maintain their structural integrity.

铁钴双（氨基膦硒化）配合物的合成及反应性

本文报道了两种金属双（氨基膦硒化物）配合物的合成，ML2 (M = Fe, Co；L = SePPh2N(−)Tol)，并研究了它们与氧原子转移试剂吡啶- n -氧化物和甲腈氧化物结合和氧化的反应性。试剂的氧化强度决定了反应性的性质：要么配体被氧化，形成双金属混合配体配合物[MLL ']n, (L ' = OPPh2N(−)Tol)，要么金属中心被氧化，形成双金属μ-氧配合物[FeL2]2（μ2-O）。本研究定义了一个化学空间，其中氨基膦硒化物配体保持其结构完整性。

期刊介绍： Organometallics is the flagship journal of organometallic chemistry and records progress in one of the most active fields of science, bridging organic and inorganic chemistry. The journal publishes Articles, Communications, Reviews, and Tutorials (instructional overviews) that depict research on the synthesis, structure, bonding, chemical reactivity, and reaction mechanisms for a variety of applications, including catalyst design and catalytic processes; main-group, transition-metal, and lanthanide and actinide metal chemistry; synthetic aspects of polymer science and materials science; and bioorganometallic chemistry.
