摘要
合成了一种带有亚氨基膦钳配体的[(POCN)Ir(H)(OAc)]配合物。该配合物对各种线性和环状烷烃具有催化转移脱氢作用，转化率合理，对正辛烷的最大转化率为 400。还可以催化 1-辛烯的异构化反应，生成内辛烯。值得注意的是，即使在 100 °C 的温度下，该催化剂也能进行催化转移脱氢反应，吨当量为 100。
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.
