The synthesis and characterization of [Pd(eta(3)-1-R-1-C3H4)FcCHN-(C6H4-2SMe)}][PF6] R-1 = H (2a) or Ph (3a)} are described. A comparative study of the catalytic activity of (a) the mixtures containing [Pd(eta(3)-C3H5)(mu-Cl)](2) and its parent ligand (1a) or H2N-C6H4-2SMe (4) and (b) the palladacycles [Pd[(eta(5)-C5H3)-CHN-(C6H4-2SMe)]Fe(eta(5)-C5H5)}Cl] (5a), [Pd(2-CH2-4,6-Me2C6H2)-CHN-(C6H4-2SMe)}Cl] (5b) in the allylic alkylation of (E)-3-phenyl-2-propenyl (cinnamyl) acetate with sodium diethyl 2-methylmalonate is also reported.
