Preparation and Stereochemistry of Cobalt(III) Complexes Containing 3,6-Diphenyl-3,6-diphosphaoctane-1,8-diamine or (2S,9S)-4,7-Diphenyl-4,7-diphosphadecane-2,9-diamine, NH2CHRCH2P(C6H5)CH2CH2P(C6H5)CH2CHRNH2 (R=H, CH3)

Nine new cobalt(III) complexes containing 3,6-diphenyl-3,6-diphosphaoctane-1,8-diamine (NPPN), trans-[CoCl2(rac(P)-NPPN)]+, cisα-[Co(L)(rac(P)-NPPN)]n+ (L=en, n=3; L=acac, n=2) and Δ- and Λ-cisα-[Co(L′)(rac(P)-NPPN)]n+ (L′=R-pn, n=3; L′=S-ala or S-pro, n=2), and five new cobalt(III) complexes containing (2S,9S)-4,7-diphenyl-4,7-diphosphadecane-2,9-diamine (SS(C)-NPPN), Δ- and Λ-cisα-[Co(L)(rac(P)SS(C)-NPPN)]n+ (L=en, n=3; L=acac, n=2) and Δ-cisβ-[Co(acac)(meso(P),SS(C)-NPPN)]2+, were prepared, where en, R-pn, acac, S-ala and S-pro denote ethylenediamine, (R)-1,2-propanediamine, 2,4-pentanedionate, (S)-alaninate and (S)-prolinate ions, respectively. Stereochemistries of the complexes and the chiral phosphorus donor atoms were studied on the basis of the absorption, 1H and 13C NMR, and CD spectra. The rac(P)-NPPN and rac(P),SS(C)-NPPN ligands formed selectively either the trans or cisα isomer, while no stable complex was obtained with the meso(P) isomers of NPPN and SS(C)-NPPN except cisβ-[Co(acac)(meso(P),...
