FORMATION OF NICKEL NANOPARTICLES AND NANOCOMPOSITES
Abstract
Nickel nanoparticles and its composites have been synthesized in a water–DMSO (1:1) mixture by reduction of Ni(NO3)2×6Н2О with sodium tetrahydridoborate. It has been found that, to obtain Ni nanoparticles in 5.0 mM Ni(NO3)2×6Н2О solution, it is best to use 5-fold excess of NaBH4. Nickel nanocomposites have been formed on the basis of polyvinylpyrrolidone (PVP), hydroxyapatite and aluminium powder. The relationship between Ni(NO3)2×6Н2О concentration and (PVP)Ni composite morphology has been established, which allows to form nickel particles of various shapes with a PVP polymeric carrier. These nickel NPs and its composites have proved to be efficient catalysts in the reaction of reductive (Na[BH(OAc)3]) amination of 4-carbomethoxybenzaldehyde with N-(2-methyl)-4-(pyridin-3-yl)pyrimidin-2,5-diamine to give methyl 4-{(4-methyl-3-(4-
(5-methylpyridin-3-yl)pyrimidin-2-ylamino)phenylamino)methyl) benzoate.
(5-methylpyridin-3-yl)pyrimidin-2-ylamino)phenylamino)methyl) benzoate.
