Abstract
The reaction of [CpIr(eta(5)-C6H5O)][BF4] (1) with PPh3 in refluxing C2H4Cl2 afforded unexpectedly but reproducibly the known compound CpI rCl2PPh3 (2) which was identified by H-1-NMR spectroscopy and single c rystal X-ray diffraction. This unexpected chemical transformation to g ive 2 involves 'C-Cl' abstraction from dichloroethane mediated by the 'CpIr' fragment. A rationale for this surprising transformation is ad vanced.
