2D NOESY studies on [Pd(η3‐C10H15){(R)( + )‐BINAP}]+ defining the relative spatial orientation of the phenyl and π‐allyl moieties

Abstract 2D NOESY, COSY and 31P,1H correlation measurements have been carried out on the optically active β‐pineneallyl‐(R)(+)‐BINAP palladium complex, [Pd(η3‐C10H15){(R)(+)‐BINAP}](CF3SO3). The ortho protons of the four non‐equivalent phenyl rings have been assigned, as have the 15 protons of the β‐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.
