Nickel(II) complexes have attracted much attention as a new generation of olefin catalysts since the α-diiminonickel complex was discovered as a highly efficient procatalyst for ethylene polymerization. A series of novel 4-arylimino-1,2,3-trihydroacridylnickel(II) dihalide complexes was synthesized in a one-pot reaction of 2,3-dihydroacridine-4-one and different anilines with nickel(II) chlorid...

Nickel allergic contact dermatitis (ACD) has become a more widely recognized disease process over the last three decades in the United States. A subpopulation of ACD patients will manifest with systemic contact dermatitis (SCD). Specifically, those cases of widespread recalcitrant nickel ACD with only partial clinical relief after strict nickel avoidance, suggest SCD. Evidence indicates that ap...

Mitochondria are important targets of metal toxicity and are also vital for maintaining metal homeostasis. Here, we examined the potential role of mitochondria in homeostasis of nickel in the roots of nickel hyperaccumulator plant Alyssum murale. We evaluated the biochemical basis of nickel tolerance by comparing the role of mitochondria in closely related nickel hyperaccumulator A. murale and ...

Butane-2,3-dione was activated towards nucleophilic addition of enecarbamates by a series of metal triflate complexes of a C2-symmetric diamine to give stereogenic, aldol-like, t-alcohols, a novel nickel(II) triflate complex was identified as a good catalyst for this asymmetric transformation, and an aquo nickel(II) complex was identified by XRD techniques.

Nickel molybdate (NiMoO₄) nanoparticles were synthesized via calcination of an oxalate complex in static air at 500 °C. The oxalate complex was analyzed by thermal gravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR). The as-synthesized nickel molybdate was characterized by Brunauer-Emmett-Teller technique (BET), X-ray diffraction (XRD), and transmission electron micros...

An atomic absorption technique is described foranalysis of nickel in serum, whole blood, urine, and other biological materials. After the sample has been subjected to protein precipitation or acid digestion, nickel is extracted into methylisobutylketone as a pyrrolidine dithiocarbamate complex, and is measured by atomic absorption spectrometry. The following values (mean ±SD) were obtained for ...

ligands derived from 8-quinoline, 6-quinoline, 1 -isoquinoline, and 5-isoquinoline were synthesized. these compounds have been used as ligands for complexation of transition metals, such as copper(ii) and nickel(ii). according to the spectrosocopic data, copper(ii) cation forms (i: 1) and (i:2) complexes with 2-(8-quinoly1)-l,l,3,3- tetramethylguanidine and 2- (i '-isoquinoly1)- 1,1,3,3-te...
