Metal complexes of unsaturated selenides. Part I. Palladium(II) and platinum(II) complexes with ligands containing the but-3-enyl and pent-4-enyl groups

Abstract

But-3-enyl butyl selenide and but-3-enyl phenyl selenide form chelate complexes of general formula [PdX₂L](X = Cl or Br) and [PtX₂L](X = Cl, Br, or I); and n-butyl pent-4-enyl selenide and pent-4-enyl phenyl selenide form chelate complexes of formula [PtX₂L](X = Cl, Br, or l), in which co-ordination to the metal occurs through both the olefinic double bond and the selenium atom. The complexes react with triphenylphosphine with replacement of the entire chelate ligand in each case.

The complexes are non-conducting in nitrobenzene. Infrared spectra are recorded and structures of the complexes are discussed.
