195Pt NMR of organoplatinum compounds

Journal of Organometallic Chemistry, 1985
Abstract The 195 Pt chemical shifts of several organoplatinum compounds in solution have been determined. The δ( 195 Pt) values of the phosphine-Pt II and -Pt 0 compounds lie in separate ranges, and allow the metal-diene systems to be characterized either as metallacyclopentene or as η 2 -bonded diene. Although the two isomers of bis(η 3 -allyl)Pt

Magnetic double-resonance studies of platinum-195 chemical shifts in organoplatinum compounds

Journal of the Chemical Society, Dalton Transactions, 1976
Platinum-195 chemical sifts and coupling constants obtained by 1H-{31P} and 1H-{195Pt} double resonance are reported for 78 platinum compounds, of which most have direct platinum–carbon bonds. Empirical trends are noted and where possible assessed in terms of current theories.

The signs of nuclear spin-spin coupling constants in some organoplatinum compounds

Journal of Organometallic Chemistry, 1979
Abstract 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 CCCF 3 ) (PPh 3 ) 2 ], [Pt(F 2 CCF 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 ...

Reactions of (π-1,5-cyclooctadiene) organoplatinum(II) compounds and the synthesis of perfluoroalkylplatinum complexes

Journal of Organometallic Chemistry, 1973
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 Hydroxo Compounds

2013
A 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.
