Giant Keplerate molecule Fe30 - the first octopole magnet
The multipole expansion technique is applied to one of the largest magnetic
molecules, Fe30. The molecule's dipole, toroid and quadrupole magnetic moments
are equal to zero (in the absence of magnetic field) so the multipole expansion
starts from the octopole moment. Probably the Fe30 molecule is the most
symmetrical magnetic body synthesized so far. The magnetization process is
considered theoretically in different geometries. Some components of the
octopole moment experience a jump while the magnetization rises linearly up to
its saturation value. An elementary octopole moment consisting of four magnetic
dipoles is proposed as a hint for designing of an experiment for measurement of
octopole magnetic moment components.Comment: 7 pages, 9 figure
The role of competition in raising the young
The article is devoted to the impact of competition on the education of youth. The author, building on work of Goncharov S. Z., analyzes the concept of «competition», «competitiveness» and «social activity», considers the relationship between competition and social activity of youth in the implementation of youth policy, traces the formation of norms of behavior of youth in the process of implementation of youth projects and programs in Nevyansk urban district of the Sverdlovsk regionРассматриваются вопросы влияния соревнования на воспитание молодежи. Автор, опираясь на работы С. З. Гончарова, анализирует понятия «соревнование», «соревновательность» и «социальная активность», взаимосвязь между соревновательностью и социальной активностью молодежи в ходе реализации молодежной политики, прослеживает формирование норм поведения молодежи в процессе реализации молодежных проектов и программ в Невьянском городском округе Свердловской област
Mild alkane fimctionalisation leading to ethers: Oxidative alkoxylation of cyclohexane with the dibromobis(phosphine)palladium(II)-sodium alkoxide system
Dibromobis(phosphine)palladium(II) complexes, PdBr2(L)2 [L = PPh3, P(p-Tol)3], react with cyclohexane and an alcoholic solution of sodium alkoxide, NaOR (R = Me, Et, Pri), at 30-60°C affording the corresponding alkyl cyclohex-1-enyl ethers, ROC6H9, in 30-140% yield on palladium both under argon and under air; benzene is inert under the reaction conditions, sodium tert-butoxide does not enter the hydrocarbon alkoxylation

Reversible thermal carbon-hydrogen bond cleavage in alkanes and arenes with dihalogenobis(triphenylphosphine)palladium(II) complexes
Dihalogenobis(triphenylphosphine)palladium(II) complexes 1, PdX 2(PPh3)2 (X = Cl, Br, I), reacts reversibly with saturated and aromatic hydrocarbons RH (RH = p-xylene, toluene, benzene, n-hexane, cyclohexane), slowly at ambient temperature and rapidly on heating at 70-130°C, to produce hydridodihalogeno(organo)bis(triphenylphosphine)- palladium(IV) complexes 2, Pd(H)(R)X2(PPh3)2; in the presence of bases complexes 2 eliminate hydrogen halide forming organobis(triphenylphosphine)palladium(II) halide 3, Pd(R)X(PPh 3)2
A Simpe Model for the Description and Prediction of the Thermodynamic Substrate and Regioselectivities of Alkane CH Activation with Metal Complexes
The empirical Pauling equation was used to develop a simple qualitative model for the description and prediction of the thermodynamic substrate and regioselectivities of alkane reactions with carbenes, nitrenes, oxene, halogens, and metal complexes. The feasibility of the model was demonstrated on examples of isomerization and transfunctionalization reactions of alkyl halides, alcohols, thiols, primary amines, and nitro compounds. A sequence of thermochemical electronegativity of simple alkyl radicals is proposed. The thermodynamic selectivity of reactions of alkanes and benzene with metal complexes was examined in terms of the developed model. It is shown that the electronic factor controlling the type of selectivity operates in a direction that depends on the electronegativity ratio between the metal-complex group attached to organic radical (χM) and hydrogen (χH). On the basis of published thermodynamic data for alkyl and phenyl derivatives of Group IV, VII, IX, X, and XII metals, the possibility of correctly predicting the substrate and regeoselectivities of hydrocarbon reactions with these compounds was substantiated
