Rhodium(III) cyclopropenylidene complexes of the type [RhCl3(PPh3)2(2,3-di(aryl)cyclopropenylidene)] (Aryl = C6H5, 4-C6H4F) are synthesized via oxidative addition of 1,1-dichloro-2,3-diarylcyclopropene fragments to rhodium(I) precursors. The molecular structure of these complexes has been determined. Attempted hydroformylation of 1-hexene with these complexes leads to catalysis results which are strongly
铑(III)的类型的cyclopropenylidene配合物[的RhCl 3(PPH 3)2(2,3-二(芳基)cyclopropenylidene)](芳基= C 6 H ^ 5,4-C 6 H ^ 4 F)通过氧化加成合成1,1-二氯-2,3-二芳基环丙烯片段形成铑(I)前体。这些配合物的分子结构已经确定。用这些络合物尝试的1-己烯加氢甲酰化导致催化结果,这强烈暗示了卡宾络合物的分解。
