TL;DR: Ag-polypyrrole nanocables were fabricated in aqueous solution at room temperature through a redox reaction between silver nitrite and pyrrole, using poly(vinyl pyrrolidone)(PVP) as assistant agent.
TL;DR: In this article, the synthesis of monodispersed Ag nanosphere particles from silver nitrite in ethylene glycol at room temperature was demonstrated with the use of an electrochemical method.
TL;DR: In this article, the addition of silver nitrite to 2-bromoalkyl phenyl selenide in the presence of mercury(II) chloride has been shown to yield conjugated nitroalkene in excellent yield.
TL;DR: In this paper, the crystal structures of 5-nitro-10,20-diphenylporphyrin, 5-bromo- 10,20diphensyl porphyreinatonickel(II), and 10-20-dimethyl-5-(trimethylsilylethynyl)porphyreynyl (5-dimethyltyl-5-SLSN) polysiliconkel(III) were determined.
Abstract: Substitutions on 5,15-diphenylporphyrin led to the isolation of mono- and di-bromo and mono- and di-nitro derivatives, which were converted into their respective nickel(II) complexes. Reaction of the bromoporphyrins with iodine/silver nitrite resulted in nitrodebromination as well as conventional nitration. The nickel(II) complex of 5-nitro-10,20-diphenylporphyrin was reduced to the 5-amino derivative. The nickel(II) complexes of the bromoporphyrins were converted into the respective mono- and bis-(trimethylsilylethynyl) species. The crystal structures of 5-nitro-10,20-diphenylporphyrin, 5-bromo- 10,20-diphenylporphyrinatonickel(II), and 10,20-diphenyl-5-(trimethylsilylethynyl)porphyrinatonickel(II) were determined.
