Synthesis of 3,3-dichloroindolin-2-ones from isatin-3-hydrazones and (dichloroiodo)benzene.
Aryl- and N-substituted isatins were converted to isatin-3-hydrazones and subjected to a dichlorination reaction with PhICl2. Lewis base-catalysis was key to the reaction occurring rapidly and chemoselectively, providing 3,3-dichloroindolin-2-ones in 49-99% yield, and offering a new approach to the deoxygenative dihalogenation reaction.
متن کاملOxidative Reactivity and Cytotoxic Properties of a Platinum(II) Complex Prepared by Outer-Sphere Amide Bond Coupling.
Benzyl amine was coupled to the dangling carboxylic acid groups of the platinum(II) complex [Pt(edda)Cl2], where edda = ethylenediamine-N,N'-diacetic acid, to give the diamidetethered complex [Pt(L)Cl2] (1), where L = ethylenediamine-N,N'-bis(N-benzylacetamide). Complex 1 was oxidized with both PhICl2 and Br2. Oxidation with PhICl2 cleanly afforded the tetrachloride complex, [Pt(L)Cl4] (2), whe...
متن کاملSynthesis of 1, 3-diaryl Substituted Iodobenzene Derivatives
The synthesis and characterization a new derivatives of 2'-iodo-meta terphenyl from the reaction ofexcess aryl-Grignard and 2, 6- dichloroiodobenzene with quenching of m-terphenyl-2'-magnesiumbromide by iodine is reported. Via the reactions three carbon-carbon bonds are constructed and mterphenylsare obtained in good yields.

The oxidation of the tribenzylphosphine derivative of the doubly cylcometallated platinum(II) complex of diphenylpyridine, 1, with PhICl2 led, as a first step, to the formation of a highly electrophilic metal centre which attacked the benzyl phosphine to give a triply cyclometallated species as the arenium ion. The highly acidic arenium ion protonated unreacted starting 1, a reaction that could...
متن کاملSynthesis, structural characterization and catalysis of ruthenium(ii) complexes based on 2,5-bis(2'-pyridyl)pyrrole ligand.
Treatment of the 2,5-bis(2'-pyridyl)pyrrolato (PDP-) anion with {Ru(COD)Cl2}n in THF readily yielded [Ru(PDP)(COD)Cl] (1) in almost quantitative yield. Anion metathesis of 1 in organic solvent by NO3- and OTf- (OTf- = triflato) gave [Ru(PDP)(COD)(NO3)] (2) and [Ru(PDP)(COD)(OTf)] (3), and in aqueous solution by BF4- and PF6- afforded aqueous complexes [Ru(PDP)(COD)(H2O)](BF4) (4+·BF4-) and [Ru(...
