Beschreibungen/Notizen
A pincer‐iridium complex bearing a Lewis‐base‐free X‐type alumanyl ligand has been synthesized. X‐ray diffraction, NMR and IR spectroscopy, as well as XANES analysis confirmed its tetrahydrido‐IrV structure and Lewis acidity at the Al center as supported by DFT calculations. The resulting complex was applied as a catalyst for the transfer dehydrogenation of cyclooctane.
Pincers et Al: The intrinsic strong σ‐donation and Lewis acidity of a Lewis‐base‐free X‐type PAlP‐pincer Ir complex has been experimentally and theoretically elucidated (X‐ray diffraction study, NMR, IR, and XANES analysis). The thermally stable pincer‐Ir complex with a tetrahydrido‐IrV structure showed moderate activity in the catalytic transfer dehydrogenation of cyclooctane.
