✦ Synopsis

Novel cationic allylpalladium(II) complexes containing the alkaloid (-)-sparteine (1) as a bidentate ligand have been prepared. Two of them, [q3-(cyclohex-2-enyl)] (sparteine)palladium(II) hexafluorophosphate ([Pd(v3-C6H,)(sparteine)][PF6]; 3b) and (sparteine)[~3-(1,1,3-triphenylallyl)]palladium(II) trifluoromethanesulfonate ([Pd(q3-Ph,CCHCHPh)(sparteine)][CF3S03]; 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.
