Triazenide complexes of iridium. Evidence for [Ir(η1-N3Ph2)(HN3Ph2)(1,5-cod)], structures of [Ir2(μ-OMe)2(1,5-cod)2], [Ir2(μ-N3Ph2)2(1,5-cod)2], [Ir(η2-N3Ph2)(H)(SiPh3)(1,5-cod)], [Ir(η2-N3Ph2)(H)(SnPh3)(1,5-cod)] and [Ir(η2-N3Ph2)(SC6F5)2(1,5-cod)]

Controllable Factors of Supported Ir Complex Catalysis for Aromatic C–H Borylation

“…The curve-fitting results of the main peak using the Ir–C/N/O parameter, along with the Ir­(OMe)­(bpy)­(cod) crystal structure, are summarized in Table . The peaks for supported Ir complexes were well-fitted, with an average Ir–/N/O bond length of 2.08 Å. , The NMR, FT-IR, and XAFS results support the proposed structures of SiO 2 -supported Ir complexes shown in Figure .…”

Rh(III)Cp* and Ir(III)Cp* Complexes of 1-[(4-Methyl)phenyl]-3-[(2-methyl-4′-R)imidazol-1-yl]triazenide (R = t-Bu or H): Synthesis, Structure, and Catalytic Activity

“…Linear triazenes containing the diazoamine group are important molecules in coordination chemistry due to their ability to form triazenide anions after deprotonation with base (Chart ). As ligands, triazenides are also very versatile due to their ability to coordinate to alkali metals, , alkaline earth metals, and early and late transition metals…”

Simple Ether‐Directed Enantioselective C(sp3)−H Borylation of Cyclopropanes Enabled by Iridium Catalysis

“…Our group has engaged in Ir‐catalyzed asymmetric C−H borylation enabled by chiral bidentate boryl ligands ( CBL s), [10f, i, k, 12] and found that in specific cases, the CBL /Ir system could also cause non‐directed C−H borylation by‐products, [12b] which indicates that, if tailored appropriately, the asymmetric C−H activation could presumably be feasible by the assistance of a highly labile DG such as simple ether. On the other hand, the existence of two bridging MeO groups in the complex [Ir(OMe)(cod)] 2 (cod: 1,5‐cyclooctadiene) [13] brought us to think and further postulate that the ether function could potentially serve as directing group in the Ir‐catalyzed C−H activation. With these considerations in mind, we envisioned that, with the right research and optimization, an Ir‐catalyzed simple‐ether directed enantioselective C−H borylation of cyclopropanes might be secured by a tailored system based on the use of CBL .…”
