Formation of organopalladium complexes on SiO2 and Al2O3 as a result of the reaction of allyl alcohol with supported PdCl2; thermal decomposition of these complexes

It was established by electronic spectroscopy in the UV and visible regions and mass spectrometry that when allyl alcohol reacts from the gas phase with palladium chloride supported on SiO2 and Al2O3 a complex similar in characteristics to a bis-π-allylpalladium chloride complex that is fixed on the surface of the support is formed. Decomposition of this complex in vacuo occurs at 135°C with the formation of allyl chloride and zero-valence supported palladium.
