Diphosphinoazines (Z,Z)-R2PCH2C(But)=NN=C(But)CH2PR2 with R Groups of Various Sizes and Complexes {[(Z,Z)-R2PCH2C(But)=NN=C(But)CH2PR2][?3 ů CH2C(CH3)=CH2)PdCl]2}.

Popis výsledku v původním jazyce

Four new ligands of diphosphinoazine type and their dioxides were synthesized and characterized. The crystal structure of dioxide of iPr2P(O)CH2C(tBu)=NN=C(tBu)CH2P(O)iPr2 which crystallizes as a solvate with one mole of hydrogen peroxide was determinedby X-ray diffraction. The ligands were used to react with bis[.mu.-chloro-(.eta.3-2-methylpropenyl)palladium] forming new binuclear palladium complexes with asymmetric .eta.3-2-methylpropenyl ligand. Phase-sensitive 2D 1H NOESY of the complexes revealedshort distance between syn protons on the terminal carbon of .eta.3-2-methylpropenyl ligand cis to phosphorus and protons of substituent groups on phosphorus for isopropyl, cyclohexyl, and tert-butyl complex. This is borne out by specifically broad resonances in 13C NMR spectra suggesting hindered rotation of substituent groups on phosphorus. The diphosphinoazines form a series with monotonnous change of chemical shifts of selected nuclei, the series is different from the literature data
