Saloutin // Journal of Fluorine Chemistry. - 2007. - Vol. 128, № 7. - P779-788 Рубрики: ХИМИЧЕСКИЕ НАУКИ Аннотация: Fluoroalkylated 1,2,3-triketone 2-arylhydrazones and 2-arylhydrazono-3-oxo esters react variously with methylamine depending on the structure of the fluorinated substituent. 2-Arylhydrazono-1,3-dicarbonyl compounds having "short" fluoroalkyl substituents condense with methylamine at the carbonyl group attached to the non-fluorinated substituent whereas ones containing a lengthy polyfluoroalkyl substituent undergo haloformic cleavage as a result of the amine addition at the carbonyl group bearing such a substituent. The resulting 2-arylazo-3-(N-methyl)amino-1-polyfluoroket-2-en-1-ones and 1-(N-methyl)amino-2-arylhydrazono-3-fluoroalkyl-3-oxopropanamides have complexing properties, and they can bind to nickel(II) and copper(II) ions. Nickel chelates can be obtained by a three-component condensation of 2-arylhydrazono-1,3-dicarbonyl compounds and methylamine in the presence of nickel(II) cations. \\\\Expert2\\nbo\\Journal of Fluorine Chemistry\\2007, v.128. p.779.pdf |

Arylhydrazones having a short fluoroalkyl substituent (RF = CF3, HCF2CF2) react at the carbonyl group adjacent to the nonfluorinated substituent to give 3-alkyl(aryl)-2-aryldiazenyl-3-methylamino-1-polyfluoroalkylprop-2-en-1-ones. Arylhydrazones with a long-chain fluoroalkyl group (RF = C3F7 and longer) and a bulky nonfluorinated group take up methylamine molecule at the carbonyl group linked to the fluorinated substituent, and the subsequent haloform reaction yields N-methyl-2-arylhydrazono-3-oxobutanamides. Both types of products are formed in reactions of methylamine with 1,2,3-triketone 2-arylhydrazones having a long fluoroalkyl group and methyl group at the other carbonyl group. Template condensation of fluoroalkyl-containing 1,2,3-trione 2-arylhydrazones with methylamine over Ni(II) template gives bis[3-alkyl(aryl)-1-polyfluoroalkyl-3-methylamino-2-aryldiazenylprop-2-en-1-onato-N,N?]-nickel(II), regardless of the size of the fluoroalkyl substituent.

Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): PETROLOGICAL MODEL -- MODELLING -- ORE -- ORE DEPOSITS Аннотация: The available data on the giant ore deposits of chromium (Kempirsai in the Urals), platinum-group metals (Bushveld in Africa), platinum-bearing copper-nickel ores (Talnakh in the Noril'sk district, northern part of the Siberian Platform), zinc-copper (massive sulfide) ores (Gai, Sibai, and Uchaly) and apatite deposits (Khibiny, the Kola Peninsula) is summarized. The giant sizes of the deposits are caused by extraordinary ore-forming processes directly associated with the highly extensive petrogenetic processes. These processes resulted in the formation of peculiar dunites in the hyperbasite complexes (chromite ores), agpaitic urtites in alkaline associations (apatite deposits), development of low-sulfide horizons and hortonolite dunites in the basite-hyperbasite layered intrusions (platinum-group metal deposits), specific processes of transmagmatic sulfurization of the iron-rich igneous differentiates (Cu-Ni sulfide and massif sulfide ores), and processes of magmatic replacement of hyperbasites that cause the alkaline agpaitic affinity of magmatism. This agpaitic tendency increases the solubility of carbon-bearing fluid components (CO2, CH4, etc.) in magma and leads to the concentration of ore metals, which form chloride-carbonate and hydrocarbon migrating compounds in the transmagmatic fluids. Some mineralogical-petrological prospecting criteria are deduced on the basis of genetic models of giant ore deposits. |
