Deprotonation of safrole in the coordination entity of platinum (II).

Abstract

The interaction  of K[Pt(Saf)Cl₃] (Saf: safrole) with AgNO₃, SnCl₂, KOH  and ethanol-water solutions was investigated. For the first time, a dinuclear chelate ring complex [Pt₂Cl₂(Saf-1H)₂], in which deprotonated safrole is bound up with platinum(II) both at benzene carbon and at ethylenic double bond of the side chain was isolated and characterized by elemental, thermal analysis, ESI MS, IR- and NMR spectroscopy.
