Electrochemical Reactions of Organic Compounds in Liquid Ammonia Part Iv. Reduction of Cyclooctatetraene
The electroreduction of COT in liquid ammonia at -38° and -65°C was investigated by cyclic voltammetric and controlled potential coulometric techniques. The results are interpreted by a two-step two-electron transfer reaction with strong ion-pairing of the COT dianion. Values for the heterogeneous electron transfer rate constants and the equilibrium constant of the disproportionation of the rad...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولBis-cyclooctatetraene tripalladium sandwich complexes.
We report synthesis and structural characterization of bis-cyclooctatetraene trinuclear palladium sandwich complexes. The non-planar cyclooctatetraene ligands flank an isosceles Pd3 triangle, which is supported by one equatorial ligand.

هدف از این مطالعه طراحی یک روش کلی برای سنتز یک سری از کمپلکس های دو هسته ای متقارن سیکلومتاله شده پلاتین (ii) بوده که دارای یک لیگاند پل زن(1,2-bis[bis(pentafluoro-phenyl)phosphino]ethane),dfppe, است. از واکنش cis-[pt(r)2(sme2)2]، که در آنr= para-tolyl ، با یک اکی والان از لیگاند benzo[h]quinoline,bhq، در استون محصول [pt(r)(bhq)(sme2)] که در آن r= para-tolyl بدست می آید. همچنین از واکنش 5/0 اک...
The Mechanism of Action of Antilturnour Platinum Compounds
As a result of observations madc by Roscnberg in the early 1960s~ a range of platinum compounds have been discovered which have significant anti-tumour properties (I, 2). The two prototype compounds originally mvcstigated are the cis isomers of diamminoplatinum(I1) dichloride and diammino-platinum(1V) tetrachloride. The stercochemistries are shown in Figure I . The t ~ m s i omers of these comp...
