2-pyridinylmethyl sulfoxides and β-imino sulfoxides was sought. The latter were obtained in tautomeric mixtures with their enamines by condensation of opticallyactive β-keto sulfoxides with primary amines. 2-Pyridinylmethyl sulfoxides were synthesized by sulfinate substitution. Titanium catalysed oxidation gave good results for the synthesis of (+)-8-(methylsulfinyl)quinoline from the corresponding

Abstract A series of coordination (Pd-NS, Pd-SNS, Pd-SNS-O) and organometallic (Pd-C and Pd-SCS) Pd(II) complexes supported by bidentate and tridentate ligands featuring sulphur moieties have been prepared. All ligands and their palladium complexes were fully characterized by various analytical techniques, including the unequivocal determination of the solid-state structures of the ligand L-SNS-O and
