An Iminophosphinite Pincer Iridium Complex: Synthesis and Catalytic Tool for Alkane Transfer Dehydrogenations

A [(POCN)Ir(H)(OAc)] complex bearing an iminophosphinite pincer ligand was synthesized. The complex showed catalytic transfer dehydrogenation of various linear and cyclic alkanes with reasonable conversions and a maximum TON of 400 for n ‐octane. A catalytic isomerization of 1 ‐octene to yield internal octenes was also possible. It is notable that the catalyst could perform catalytic transfer dehydrogenation even at a temperature of 100 °C with a TON of 100.
