Potassium trichloro(safrole)platinate(II), K[Pt-(Saf)Cl₃] (1), reacts with piperidine to give cis-[Pt(Saf1H)(Piperidine)Cl] (2). The interaction of 1 with AgNO₃, SnCl₂, KOH, and ethanol-water solutions leads to formation of the dinuclear chelate ring complex [Pt ₂(Saf-1H)₂Cl₂] (3). ₁H and ₁₃C NMR spectra and single-crystal X-ray diffraction show that in complexes 2 and 3 deprotonated safrole is bound up with platinum(II) both at a benzene carbon and at the ethylenic double bond of the side chain. © 2008 American Chemical Society.
