چکیده
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.

Chiral thiolate complexes [Cp(NO)(Ph3P)ReSCH2R] (R = Ph, 4-C6H4Cl, 4-C6H4OMe, H, Me) are obtained from [Cp(NO)(Ph3P)ReCH3] by acid cleavage in the presence of thiol and subsequent deprotonation. Small amounts of (chloromethyl)thioether complexes [Cp(NO)(Ph3P)ReS(CH2Cl)CH2R]BF4 are formed when dichloromethane is used as a sol vent in this reaction. Hydride abstraction using [Ph3C]PF6 converts t...
