2D-NOESY STUDIES ON [PD-ETA(3)-C10H15)((R)(+)-BINAP)]+ DEFINING THE RELATIVE SPATIAL ORIENTATION OF THE PHENYL AND PI-ALLYL MOIETIES

2D NOESY, COSY and P-31, H-1 correlation measurements have been carried out on the optically active beta-pineneally-(R)(+)-BINAP palladium complex, [Pd(eta-3-C10H15){(R)(+)-BINAP}](CF3SO3). The ortho protons of the four non-equivalent phenyl rings have been assigned, as have the 15 protons of the beta-pineneallyl. The 2D NOE data show selective interactions of the phenyl ortho protons with different sections of the allyl ligand, thereby contributing to our knowledge of the three-dimensional solution structure of this cationic complex.
