Oxidation of 1 or 2 with hydrogen peroxide, elemental sulfur or gray selenium affords the corresponding chalcogen derivatives. The palladium and platinum complexes of these P-N-P donor ligands were prepared by the reaction of the bis(phosphino) amines with MCl2(cod) (M = Pd or Pt, cod = cycloocta-1,5-diene). All the new compounds have been characterized by analytical and spectroscopic methods, including H-1-P-31 NMR, H-1-C-13 HETCOR, or H-1-H-1 COSY correlation experiments. The Pd(II) complexes were investigated as catalysts in the Suzuki and Heck reactions; both showed good catalytic activity affording high yields of the desired products.eninfo:eu-repo/semantics/closedAccess[No Keyword]Article365513520WOS:0002936447000082-s2.0-8005155130810.1007/s11243-011-9497-8Q2Q3
