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.
顺式-(三苯基膦)₂氯化铂和顺式-(三苯基膦)₂碳酸铂是在无溶剂条件下由固体反应物通过机械化学法制备的；多晶氯化铂和三苯基膦球磨后，以98%的产率得到顺式-(三苯基膦)₂氯化铂；顺式-(三苯基膦)₂氯化铂与过量无水碳酸钾的机械诱导固态反应以70%的产率生成顺式-(三苯基膦)₂碳酸铂；通过固态³¹P MAS NMR光谱、X射线粉末衍射和差示热分析证实了机械化学无溶剂反应生成过渡金属配合物。
