| Abstract: | The chloro bridges in di-μ-chloro-4-methoxy- and di-μ-chloro-4-acetoxy-2-methyl-but-2-enylchloropalladium are split by Group V donor ligands Ph3E (where E = P, As and Sb) to give [(η)3-H2CC(CH3)CHCH2X) PdCl · EPh3], (where X = OCH3, OCOCH3). These complexes are readily decomposed by dilute ethanolic hydrogen chloride yielding [Ph3E · PdCl]2 and isoprene. The structures of the compounds are discussed in the light of their 1H NMR spectra. |
