General Description

Potassium trichloro(ethylene)platinat(II) monohydrate is a chemical compound with the formula K[PtCl3(C2H4)].H2O. POTASSIUM TRICHLORO(ETHYLENE)PLATINATE (II) MONOHYDRATE is a coordination complex with a platinum(II) atom surrounded by three chlorine atoms and one ethylene ligand. The presence of a potassium cation and a water molecule suggests that this compound is a hydrate. It is commonly used as a catalyst in organic synthesis reactions, particularly in the formation of carbon-carbon bonds. Its structure and properties make it a versatile and important compound in the field of chemistry and materials science.

A fast and easy approach to the synthesis of Zeise's salt using microwave heating

A fast and easy approach to the synthesis of Zeise's salt, KPtCl3(C2H4), is reported using microwave heating. The reaction is complete after 15 min at 130 °C using K2PtCl4 as starting material, a 1:1:

Formation and decomposition of the methylplatinum(IV) complex in the mechanically activated K2PtCl4 powder-MeI vapor system

Mechanical treatment of the K2PtCl4 solid salt in a vibrating mill results in Pt-Cl bond heterolysis to form coordinatively unsaturated Pt(II) complexes. At room temperature, the freshly treated K2PtCl4 salt absorbs methyl bromide and evolves methyl chloride to the gas phase. The reaction mechanism involves the following sequence of steps: the oxidative addition of methyl iodide to Pt(II) with the intermediate formation of Pt(IV) methyl complexes and the decomposition of the latter due to intramolecular reductive elimination with methyl chloride formation. The first step of the reaction of MeI with the preactivated surface of the K2PtCl4 salt is assisted by active sites, which are regenerated in each act of the chemical transformation of MeI into MeCl involving in the chain substitution of halogen in methyl iodide. The coordinatively unsaturated surface platinum complexes can act as such active sites. Due to their effective positive charge, they can provide electrophilic assistance to nucleophilic substitution. Chain termination is probably due to the coordination of the complex with a coordination vacancy and an interstitial chloride ion to the inactive K2PtCl4 complex.

Highly selective metal mediated ortho-alkylation of phenol. First platinum containing organometallic chromane analogues

We were able, for the first time, to synthesize and characterize Pt derivatives with a structural shape similar to vitamin E, having a metalla-chromane core. The formation reaction mechanism includes an unexpected highly selective ortho aromatic electrophilic substitution on phenol, operated by [PtCl(η1-C2H4OR)(N-N)], R = Me or Ph, and a final cyclization step. The X-ray structure of one of the new metalla-chromane complexes [Pt(EtPh)(phen)], 1a, (EtPh = 2-(ethan-2′-yl- kC1)-1-phenolato-kO1, phen = 1,10-phenanthroline) is reported. Cytotoxicity and Pt uptake measurements, performed on HeLa cancer cells, show an interesting structure-activity correlation for the new metalla-chromane analogues 1a and [Pt(MeOEtPh)(phen)], 1b, (MeOEtPh = 2-(ethan-2′-yl-kC1)-4-(methoxy)-1-phenolato-kO1), being the structurally closest to vitamin E and also the most active.
