Monothio-?-diketones with a 1,1,2,2-tetrafluoroethyl moiety and their metal chelates

Autor: K. I. Pashkevich, A. L. Nikol'skii, I. Ya. Postovskii

Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 26:1536-1539

1. The reaction of polyfluorinatedβ-diketones with H2S gave monothio-β ldiketones with a 1,1,2,2-tet-rafluoroethyl moeity. 2. The obtained monothio-β-diketones exist completely in the enthiol form.

Predicting the technological properties of uranium ores in natural deposits on the basis of a regression model

Autor: P. V. Pribytkov, A. A. Deryagin, A. L. Nikol'skii, N. A. Drobysheva, L. A. Orlova

Publikováno v: Soviet Atomic Energy. 48:251-255

The technological properties of ores are characterized by spatial variability, the level of which depends on the geological-struc tural and mineralogical-ge ochemical conditions of localization of the deposit. For most deposits of nonferrous, rare, t

Autor: I. G. Busygin, A. L. Nikol'skii, V. A. Gindin, K. I. Pashkevich

Publikováno v: Bulletin of the Academy of Sciences of the USSR Division of Chemical Science. 33:832-834

1. The hindered rotation of the unsubstituted amino group around the N-C= bond in fluorinated β-aminovinyl thiones with a gem arrangement of the RF and NH2 groups was established. 2. The activation parameters of this process are but slightly depende
