Linke, Alexander;Decker, David;Drexler, Hans-Joachim;Beweries, Torsten research published 《 Iridium(III) bis(thiophosphinite) pincer complexes: synthesis, ligand activation and applications in catalysis》, the research content is summarized as follows. Iridium(III) bis(thiophosphinite) complexes of the type [(^RPSCSP^R)Ir(H)(Cl)(py)] (^RPSCSP^R = κ³-(2,6-SPR₂)C₆H₃) (R = tBu, iPr, Ph) can be prepared from the ligand precursors 1,3-(SPR₂)C₆H₄ by C-H activation at Ir using [Ir(COE)₂Cl]₂ or [Ir(COD)Cl]₂. Optimization of the protocol for complexation showed that direct cyclometallation in the absence or presence of pyridine, as well as C-H activation in the presence of H₂ are viable options that, depending on the phosphine substituent furnish the five-coordinate Ir(III) hydride chloride complexes 2–R or the base stabilized species 3–R in good yields. In case of the ^PhPSCSP^Ph ligand, P-S activation results in the formation of a thiophosphine stabilized Ir(III) hydride complex [(^PhPSCSP^Ph)Ir(H)(Cl)(PPh₂SH)] (4). Reaction of 2-tBu with H₂ in the presence of base furnishes an Ir(III) dihydride complex (5) via a labile Ir(III) dihydride-dihydrogen complex (6). All complexes are inactive for transfer dehydrogenation of cyclooctane in the presence of NaOtBu and tert-butylethylene, likely due to decomposition of the Ir complex in the presence of base at higher temperature

Herein, an Ir-catalyzed asym. allylic substitution reaction of Me azaarenes was described. Azaarenes such as (benzo)thiazole, oxazole, benzoimidazole, pyridine, and (iso)quinoline were all tolerated. The corresponding chiral azaarene derivatives were obtained in good yields with high enantioselectivity (up to 96% yield and 99% ee). The utilization of the Knochel reagent TMPZnBr·LiBr warranted the in situ formation of benzylic nucleophiles without addnl. activating reagents. NMR studies suggested a two-fold function of the Knochel reagent in this reaction. The synthetic utility of this method was showcased by a concise enantioselective synthesis of an allosteric protein kinase modulator.
