Rearrangement of co-ordinated cyclo-octadienes in palladium(II) and platinum(II) complexes

Abstract

Cyclo-octa-1,3-diene reacts with dichlorobis(benzonitrile)palladium(II) to give a mixture of dichlorocyclo-octa-1,5-dienepalladium(II) and dichlorocyclo-octa-1,4-dienepalladium(II), whereas with Pt^II only the cyclo-octa-1,5-diene complex is obtained: evidence for the formation of cyclo-octa-1,4-diene during the rearrangement of cyclo-octa-1,3-diene to cyclo-octa-1,5-diene in the palladium system is presented.
