Ortho-(methylsulfanyl)phenylphosphonates and derivatives: Synthesis and applications as mono- or bidentate ligands for the preparation of platinum complexes

Popis výsledku v původním jazyce

The preparation of six phenylphosphonates (and phosphonic acid derivatives) bearing a sulfur group in ortho position was accomplished via either a [1,3]- or a [1,4]-sigmatropic rearrangement. Their complexation with different platinum sources has been studied and the new platinum complexes obtained were characterized by NMR spectroscopy (1H, 13C, 31P and 195Pt). Three runs of experiments were performed. The first was the reaction of ligands 1 and 2 bearing one sulfide and a phosphonate diester functionswith potassium tetrachloroplatinate. In the obtained complexes, two molecules of ligand chelate the metal only by the sulfur atom. We were able to observe by 195Pt and 31P NMR spectroscopy the trans to cis rearrangement of a dichloro-methyl-(o-phosphorylbenzyl)sulfide platinum(II) complex upon time, leading to two new species, which are diastereomers of the cis-complex.
