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 on the meta-isomer sandwich was more facile than substitution of the chloro on the ortho-isomer sandwich, contrary to the observed reactivity pattern in the free arenes.
