报道了一系列以bis(2-diisopropylphosphinophenyl)-2-anisoylmethane(PCanisHP)为基础的IrPCSP3P配合物。(PCanisP)Ir(H)Cl是由[Ir(COD)Cl]2(COD=1，5-环辛二烯)通过C-H活化生成的，而(PCanisP)Ir(H)2是由(PCanisP)Ir(H)Cl通过氢化物歧化反应生成的。两种配合物均为18E八面体配合物，具有良好的水稳定性。用CO和PMe3考察了苯甲醚的半衰性，生成了多个取代苯甲醚取代基的异构体，显示了配体主链的柔韧性。在C6D6中，(PCanisP)Ir(H)2在中等温度下显示出在氢化物、主链和苯甲醚位置掺入了氢。(PCanisP)Ir(H)Cl和(PCanisP)Ir(H)2都是温和条件下环辛烷转移脱氢的预催化剂。
A series of iridium PCsp3P complexes based on bis(2-diisopropylphosphinophenyl)-2-anisoylmethane (PCanisHP) is reported. (PCanisP)Ir(H)Cl was generated from the C–H activation of the backbone by [Ir(COD)Cl]2 (COD = 1,5-cyclooctadiene), while the dihydride (PCanisP)Ir(H)2 was generated by hydride metathesis from (PCanisP)Ir(H)Cl. Both complexes are 18e octahedral complexes and water stable. The hemilability of the anisole tether was probed using CO and PMe3; multiple isomers, in which the anisole substituent was displaced, were generated, showing the flexibility of the ligand backbone. (PCanisP)Ir(H)2 showed deuterium incorporation in the hydride, backbone, and anisole positions upon moderate heating in C6D6. Both (PCanisP)Ir(H)Cl and (PCanisP)Ir(H)2 were precatalysts for transfer dehydrogenation of cyclooctane under moderate conditions.
