The signs of nuclear spin-spin coupling constants in some organoplatinum compounds
Journal of Organometallic Chemistry, 1979Abstract The signs and magnitudes of the electron-mediated nuclear spin-spin coupling constants involving 1 H, 19 F, 31 P and 195 Pt have been measured in the representative organoplatinum species [Pt(CF 3 CCCF 3 ) (PPh 3 ) 2 ], [Pt(F 2 CCF 2 )(PPh 3 ) 2 ] and [{Pt(Me)(PMe 2 Ph)μ(SMe)} 2 ] by means of 1 H-{ 31 P}, 1 H-{ 195 Pt}, 19 F-{ 31 ...

The bioorganometallic platinum(II) compounds PtU6 and PtU5 were designed by the conjugation of the corresponding uracil derivative and the organoplatinum(II) compound [4-octyloxy-(C^N^N)PtCl]. The single crystal X-ray structure determination of PtU6 revealed the formation of the dimeric structure through intermolecular hydrogen bonds between the uracil

EPR study of electron transfer and group transfer in organoplatinum(II) and (IV) compounds †
Journal of the Chemical Society, Perkin Transactions 2, 1997Chelate complexes between the 1,4-diazabuta-1,3-diene ligands RNCH–CHNR = R–DAB (R = alkyl, aryl) and the organoplatinum fragments PtMe2, PtMe4 and PtMes2 (Mes = mesityl) can be reversibly reduced to paramagnetic compounds, formulated as platinum(II) or (IV) species bound by radical anion ligands (R-DAB˙–).

Organoplatinum Hydroxo Compounds
2013A series of monomeric platinum (II) hydroxo supported by bulky diimine ligands have been synthesized and fully characterized. A thorough investigation of their corresponding reactivity have been carried out to determine if they participate in a water splitting cycle.

Abstract An improved synthesis for the complexes PtR 2 (COD), [where COD = 1,5cyclooctadiene, R = I, CH 3 , C 2 H 5 , CH 2 C 6 H 5 , CH 2 Si(CH 3 ) 3 , C 6 H 5 ] and the reactions with HCl (generated in situ ) to give PtRCl(COD) are described. The coupling constant J(Pt-H) to the olefinic carbons varies with the trans -influence of the trans ...

[Organoplatinum compounds. 1987 update].
Nouvelle revue francaise d'hematologie, 1988Cisplatin is one of the best available cytotoxic agents particularly in testicular, ovarian and head and neck cancer. However gastrointestinal and renal toxicities preclude greater utilisation. High dose cisplatin (200 mg/m2) has serious neurological side effects.

AbstractThe complexation of appropriate organoplatinum compounds by water‐soluble polymers has the potential to provide a time‐release formulation which might afford a substantial reduction in the severity of side effects associated with use of organoplatinum antitumor agents. Both poly‐(N‐vinylpyrrolidone)(PVP) and poly(N‐vinyl‐5‐methyl‐2‐oxazolidone)(

The work described in this thesis stems from the observation that a pyrazolyl group in Me2Pt(HCpz3) umdergoes a Cyclometallation reaction when heated in neat pyridine, giving rise to a NC- coordination mode, which is uncommon for flexible carbon bridged maltidentate ligands....

Over the past couple of decades, coordination-driven self-assembly has evolved as a broad multidisciplinary domain that not only covers the syntheses of aesthetically pleasing supramolecular architectures but also emerges as a method to form new optical materials, chemical sensors, theranostic agents, and compounds with light-harvesting and emissive ...
