 Effect of Uncoordinated Tertiary Nitrogen Atoms in Hexaaza Macrocyclic Nickel(II) Complexes on Axial Binding of Anions ...   (Site not responding. Last check: 2007-11-05)
Axial coordination of anions or water to the square-planar nickel(II) complexes of the hexaaza macrocyclic ligands ^{1, 2} and ^{3}, which contain two extra uncoordinated tertiary nitrogens, have been investigated in aqueous solutions containing HX (X=Cl^{-}, Br^{-}, NO_{3}^{-}, or ClO_{4}^{-}) and/or NaX.
The nickel(II) complexes exist in the acidic solutions as equilibrium mixtures of the square-planar [Ni(L)]^{2+} (L=1, 2, and 3) and octahedral species [Ni(H_{2}L)X_{2}]^{2+} (H_{2}L=diprotonated form of L).
The conversion of square-planar to octahedral species for the nickel(II) complexes of 1-3 were observed with the electronic spectra in aqueous solutions containing various acids.

 Nickel (IARC Summary & Evaluation, Volume 49, 1990)
Enhanced frequencies of chromosomal gaps and/or anomalies were observed in single studies in peripheral blood lymphocytes of employees engaged in: (i) crushing, roasting and smelting (exposure mainly to nickel oxide and nickel subsulfide); (ii) electrolysis (exposure mainly to nickel chloride and nickel sulfate); and (iii) electroplating (exposure to nickel and chromium compounds).
Nickel chloride and nickel nitrate were inactive in assays in vivo for induction of dominant lethal mutation and micronuclei, and nickel sulfate did not induce chromosomal aberrations in bone-marrow cells; however, nickel chloride induced chromosomal aberrations in Chinese hamster and mouse bone-marrow cells.
Chromosomal aberrations were induced in mammalian cells by nickel chloride, nickel sulfate and nickel acetate, and sister chromatid exchange was induced by nickel chloride and nickel sulfate.

 Palladium (EHC 226, 2002)
In this study, it remained unclear whether reactivity to palladium(II) chloride in animals sensitized with nickel sulfate was due to cross-reactivity or to the induction of sensitivity by the repeated treatments.
Mice given palladium(II) chloride (5 mg Pd /litre) in drinking-water from weaning until natural death developed malignant tumours, mainly lymphoma-leukaemia types and adenocarcinoma of the lung, at a statistically significant rate, but concomitant with an increased longevity in males, which may explain at least in part the increased tumour rate.

In soil, the mobility of platinum depends on the pH, redox potential, chloride concentrations of soil water, and the mode of occurrence of platinum in the primary rock.
For both the simple platinum salts and cisplatin, it has been established that there is an initial rapid clearance followed by a prolonged clearance phase during the remaining post-exposure period, and that there is no evidence for markedly different retention profiles.

 Patent 4124627: Trans-fluoro(pentafluorophenyl)-bis(triethylphosphine)nickel(II)
The oxidative-addition of organic chlorides, bromides, and iodides to low valent transition metal complexes is an important method of synthesis in organometallic chemistry.
The reaction is often facile with organic iodides and usually very difficult with organic chlorides.
For example, the oxidative-addition of pentafluorochlorobenzene or pentafluorobromobenzene to 1,5-cyclooctadienebis(triethylphosphine)-nickel(O) results in the formation of pentafluorophenylbis(triethylphosphine) nickel(II) chloride or bromide respectively.

 Reduction of Nitriles to Primary Amines with Nickel Boride at Ambient Temperature
The nickel boride was generated in situ from dry nickel(II) chloride and sodium borohydride and the reductions were carried out in dry ethanol.
The reductions are very rapid and are complete in ~5 min, as monitored by thin layer chromatography, using 1:1:3 molar ratio of substrate to nickel(II) chloride to sodium borohydride, Eq.
The reductions are thus undoubtedly proceeding due to the involvement of both reagents i.e., the nickel boride formed in situ.
