Platinum-Catalysed Cyclopropanation of Olefins with Ethyl Diazoacetate

Abstract The addition of ethyl diazoacetate to olefins in the presence of a catalytic amount of platinum complexes provides the corresponding cyclopropanes in good to excellent yields.

Nano-sized octa-nuclear nickel cationic complex: self-assembly on supramolecular level

Abstract Microporous one-dimensional material was synthesized by reacting Ni-9 cluster compound Ni9(HOOCCMe3)4(μ4-OH)3(μ3-OH)3(OOCCMe3)12 with organic ligand 3-(3,5-dimethylpyrazol-1-yl)-6-(3,5-diamino-1,3,4-thiadiazolyl)-1,2,4,5-tetrazine) (L). According to X-ray data, the nano-sized endless tubes of the material consist of stacked cationic Ni(II) octa-nuclear cyclic complexes of formula [Ni8(μ-OH2)4(μ-OOCCMe3)4(η2-OOCCMe3)(OOCCMe3)10L4]+ and pivalate anions ordered regularly aside the tubes. The channels of the tubes are filled with acetonitrile molecules forming an inclusion compound.

Insertion of carbenes into OH bonds of alcohols catalysed by platinum complexes

Abstract The addition of diazoesters to alcohols in the presence of a catalytic amount of platinum complexes provides the corresponding Oue5f8H insertion products in good to excellent yields.

Oxygen initiated unprecedented condensation of propargylamine into the 1,3-di(propargylimino)propylateanion coordinated to cobalt(III)

Condensation of coordinated propargylamine into the nunprecedented 1,3-di(propargylimino)propylateanion, an analogue of the nacetylacetonate anion, is initiated by dioxygen in the Co(II) npolymeric trimethylacetate complex/NH2CH2CCH nsystem; molecular structures of the intermediate complex, nCo(O2CCMe3)2(H2NCH2 nCCH)4 and final product nCo(O2CCMe3)2(NH2CH2 nCCH)2[N,N′-(HCCCH n2NCHCHCHNCH2CCH)] were established by X-ray nanalysis.
