Abstract
Novel cationic allylpalladium (II) comp, exes containing the alkaloid (−)sparteine (1) as a bidentate ligand have been prepared. Two of them, [η3(cyclohex‐2‐enyl)] (sparteine)palladium(II) hexafluorophosphate([Pd(η3‐C6 H9)(sparteine)][PF6] 3b) and (sparteine)[η3‐(1,1,3‐triphenylallyl)] palladium (II) trifluorophosphate ([Pd(η3‐Ph2CCHCHPh)(sparteine)][sparteine)] [CF3SO3]; (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.Keywords
