Abstract

Reaction of [(coe)₂IrCl]₂ (coe = cyclooctene) with AgPF₆, arene (toluene, p-xylene, mesitylene), and diphenylacetylene, followed by counter anion exchange to BARF^–, gives cyclobutadiene iridium complexes [(C₄Ph₄)Ir(arene)]BARF in 10–22% yield. Replacement of toluene in [(C₄Ph₄)Ir(toluene)]BARF by various ligands (trimethyl-phosphite, 1,3,5-triaza-7-phosphaadamantane, tert-butyl isonitrile) provides access to the half-sandwich cyclobuta-diene iridium complexes [(C₄Ph₄)Ir(L)₃]BARF. Complex [(C₄Ph₄)Ir(toluene)]BARF in combination with [NBnEt₃]Cl catalyses the insertion reaction between phenyl diazoacetate and various amines.

四苯基环丁二烯铱络合物的合成、反应性和催化应用

将[(coe)2IrCl]2（coe = 环辛烯）与 AgPF6、炔（甲苯、对二甲苯、间二甲苯）和二苯基乙炔反应，然后进行反阴离子交换至 BARF-，可得到环丁二烯铱配合物[(C4Ph4)Ir(arene)]BARF，收率为 10-22%。用各种配体（亚磷酸三甲酯、1,3,5-三氮杂-7-磷杂金刚烷、叔丁基异腈）取代[(C4Ph4)Ir(甲苯)]BARF 中的甲苯，可得到半三明治环丁二烯铱络合物[(C4Ph4)Ir(L)3]BARF。络合物[(C4Ph4)Ir(甲苯)]BARF 与[NBnEt3]Cl 结合可催化重氮乙酸苯酯和各种胺之间的插入反应。

期刊介绍： Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
