Air- and moisture-stable cationic (diphosphine)palladium(II) complexes as hydroamination catalysts: X-ray crystal structures of two [(diphosphine)Pd(NCMe)(OH2)]2+[OTf]−2 complexes

A series of cationic (diphosphine)palladium(II) complexes have been prepared and fully characterized, including two crystal structures. These complexes were evaluated as catalysts for the hydroamination of acyclic alkenes. The reactivity of the catalysts is dependent on the nature of the diphosphine ligand and the substituents on the amine and alkene substrates.
