The ortho, meta and para complexes of bis(η6-chlorobenzotrifluoride)chromium(0) were made by metal-vapor synthesis. Nucleophilic substitutions by thiophenoxide of these complexes are compared to nucleophilic substitutions by thiophenoxide on the uncoordinated arenes. It was found that substitution at the chloro position is more facile on the complexes than on the free arenes. Substitution of the chloro
的邻位,间和对位二复合物(η 6 -chlorobenzotrifluoride)铬(0)通过金属蒸气合成作了。在未配位的芳烃上,将噻吩对这些配合物的亲核取代与噻吩对亲核的取代进行了比较。已经发现,与游离芳烃相比,配合物在氯位置的取代更容易。上的氯的取代间位异构体三明治比对的氯的取代更容易的邻位异构体三明治,相反在自由芳烃所观察到的反应性模式。
