Novel cationic allylpalladium (II) comp, exes containing the alkaloid (−)sparteine ( 1 ) as a bidentate ligand have been prepared. Two of them, [η 3 (cyclohex‐2‐enyl)] (sparteine)palladium(II) hexafluorophosphate([Pd(η 3 ‐C 6 H 9 )(sparteine)][PF 6 ] 3b ) and (sparteine)[η 3 ‐(1,1,3‐triphenylallyl)] palladium (II) trifluorophosphate ([Pd(η 3 ‐Ph 2 CCHCHPh)(sparteine)][sparteine)] [CF 3 SO 3 ]; ( 3c ) were characterized by X‐ray diffraction. The application of 2D‐NMR methods (COSY and NOESY)affords a correlation between the solid‐state and solution structures for complex 3c .
