chlorinating reagent used [Mo(CpBz)(η2-COCH3)Cl3], 3, [W(CpBz)Cl4], 4, [Mo(CpBz)(CO)3Cl], 5 and [Mo(CpBz)Cl4], 6 have been obtained. The molecular structures of all compounds are reported and two conformations have been characterised for the benzyl substituents. In complexes 2a, 2b and 5 one phenyl ring bends towards the metals while in 3 and 4 the five phenyls point opposite to the metals.
制备了[M(CpBz)(CO)3 CH 3 ](M = Mo,2a,W,2b; CpBz = C 5(CH 2 Ph)5),并使其与PCl 5和PhI·Cl 2反应。取决于金属和所使用的氯化剂[沫(CpBz)(η 2 -COCH 3)氯3 ],3,[W(CpBz)氯4 ],4,[沫(CpBz)(CO)3 CL] ,5和[Mo(CpBz)Cl 4 ],6已获得。报道了所有化合物的分子结构,并已表征了苄基取代基的两个构象。在配合物2a,2b和5中,一个苯环向金属弯曲,而在化合物3和4中,五个苯基与金属相反。
