substituent to form (in low yields) the corresponding mononuclear complex or binuclear complexes with both the aromatic ring of paracyclophane and the aryl ring of the substituent involved in coordination. The structure of such complex, namely, [4-(η6-2,4,6-trimethylpheny)-11-16-η6-[2,2]paracyclophane]bis[tricarbonylchromium(0)] was confirmed by X-ray diffraction study.
已经研究了单芳基和二芳基取代的 [2.2] 对环芳烃与 (NH3)3Cr(CO)3 的络合反应。[2.2]对环芳的芳环比芳基取代基更利于配位。这导致相应的单核或双核三羰基铬配合物的区域选择性形成。在某些情况下,三羰基铬基团与取代基的芳环配位以形成(以低产率)相应的单核配合物或双核配合物,其中对环芳的芳环和取代基的芳环参与配位。通过X射线衍射证实了这种配合物的结构,即[4-(η6-2,4,6-三甲基苯基)-11-16-η6-[2,2]对环芳烷]双[三羰基铬(0)]学习。
