The results of studies on the separation of platinum(IV) ions by solvent extraction from aqueous solutions after leaching of spent catalysts have been reviewed. The following processes have been discussed: acid leaching of spent catalysts and solvent extraction of platinum(IV) ions by using organophosphorous acids, amines and oximes as the extractants. In hydrometallurgical leaching of spent au...

the binding energy and thermodynamic parameters of cis- platinum di ammino chlorine (cis-[pt(nh3)2cl]+) and trans- platinum di ammino chlorine (trans- [pt(nh3)2cl]+) complexes withguanine has been studied by density functional theory (dft) calculations in water. the bindingenergies (ebin) of cis- and trans-[pt(nh3)2clg]+ are calculated to be 79.38 kcal/mol and 74.98kcal/mol, respectively. the b...

Reactions of fac-[PtMe3(4,4'-R2bpy)(Me2CO)][BF4] (R = H, 1a; tBu, 1b) and fac-[PtMe3(OAc-kappa2O,O')(Me2CO)] (2), respectively, with thioglycosides containing thioethyl (ch-SEt) and thioimidate (ch-STaz, Taz = thiazoline-2-yl) anomeric groups led to the formation of the carbohydrate platinum(IV) complexes fac-[PtMe3(4,4-R2bpy)(ch*)][BF4] (ch* = ch-SEt, 8-14; ch-STaz, 15-23) and fac-[PtMe3(OAc-k...

Erratum to “Synthesis, characterization and crystal structure of platinum(II) complexes with thiourea derivative ligands” [Eur. J. Chem. 9 (4) (2018) 360-368].

The Pt(IV) diazido complex trans,trans,trans-[Pt(N(3))(2)(OH)(2)(pyridine)(2)] (1) is unreactive in the dark but is cytotoxic when photoactivated by UVA and visible light. We have shown that 1 when photoactivated accumulates in tumor cells and binds strongly to nuclear DNA under conditions in which it is toxic to tumor cells. The nature of the DNA adducts, including conformational alterations, ...

Photoredox catalysis is employed to design unprecedented C6?-functionalized 6-aryl-2,2?-bipyridines prepare (circularly polarized) luminescent cyclomatalated platinum(ii) complexes.

Two series of heteroleptic cyclometalated platinum(II) complexes [(C(n)Oppy)Pt(acac) and (C(n)OFppy)Pt(acac)] have been prepared. Their liquid-crystal and optophysical properties were studied, in which C(n)Oppy is 2-(4-alkoxyphenyl)-5-(alkoxymethyl)pyridine and C(n)OFppy is 2-(3-fluoro-4-alkoxyphenyl)-5-(alkoxymethyl)pyridine. Only the heteroleptic cyclometalated platinum(II) complexes (n = 12 ...
