Abstract

The complexes [(η3-C6H9)Pd(η2-S2CNR2)] (R = Me, 1; Et, 2), [(η3-Me2CCMeCH2)Pd (η2-S2COEt)] 3 and [(η3-Me2CCMeCH2)Pd(η2-S2PPh2)] 4 have been synthesized by reaction of [(η3-allyl)Pd(μ-Cl)]2 with NaS2CNR2 (R = Me, Et), KS2COEt and NaS2PPh2. They have been characterized by elemental analysis, FTIR, 1H NMR and FAB mass spectrometry. Spectroscopic studies suggest that sulfur donor ligands are bidentate, forming Pd–S–C–S and Pd–S–P–S palladacycles, an η3-allyl group completing the coordination sphere.
