, p. 25 - 33 (2001)
Four multitopic ligands, N,N′-bis[(S)-prolyl)phenylenediamine, N,N′-bis{[(S)-pyrrolidin-2-yl]methyl}phenylenediamine, N,N′-bis[(S)-N-benzylprolyl]phenylenediamine, N,N′-bis{[(S)-N-benzyl-pyrrolidin-2-yl]methyl}phenylenediamine, were synthesised and their co-ordination properties with Rh(I) and Ir(I) studied. The complexes were prepared by the reaction of [MCl(cod)]2 with AgPF6 and further treatment with the ligand. All ligands form one to one [ML] species with the above metal ions. The structures of these complexes were elucidated by analytical and spectroscopic data (elemental analysis, mass spectroscopy, IR, 1H- and 13C-NMR). Complexes show excellent activities and enantioselectivities up to 30% for the hydrogenation of prochiral olefins under mild reaction conditions.
Nickel(II) complexes with amide ligands: Oxidative dehydrogenation of the amines in a tetradentate diamide-diamine ligand
Weeks, Colin L.,Turner, Peter,Fenton, Ronald R.,Lay, Peter A.
, p. 931 - 940 (2007/10/03)
Four complexes were prepared by the reaction of Ni(II) with three pyrrolidine based diamide-diamine ligands. The two amine groups in the ligand N,N′-bis(S-prolyl)-1,2-ethanediamine (S,S-bprolenH2) were oxidatively dehydrogenated during the prep
