Abstract

Cis-(Ph₃P)₂PtCl₂ and cis-(Ph₃P)₂PtCO₃ were prepared mechanochemically from solid reactants in the absence of a solvent; cis-(Ph₃P)₂PtCl₂ was obtained in 98% yield after ball-milling of polycrystalline PtCl₂ and Ph₃P; the mechanically induced solid-state reaction of cis-(Ph₃P)₂PtCl₂ with an excess of anhydrous K₂CO₃ produced cis-(Ph₃P)₂PtCO₃ in 70% yield; the formation of transition metal complexes as a result of mechanochemical solvent-free reactions has been confirmed by means of solid-state ³¹P MAS NMR spectroscopy, X-ray powder diffraction and differential thermal analysis.
