Chemistry of xenon derivatives. Synthesis and chemical properties

Abstract

The critical relaxation of the four-state Potts model on L x L lattices with L 5 64 is studied by the Monte Carlo method. The decay of the magnetisation from a nonequilibrium initial state exhibits a crossover from a power-law relaxation for I<< r ' ( L ) to an exponential one for r > > f ' ( L ) ,where t ' ( L ) is some crossover time. This crossover is discussed within the context of dynamic finite-size scaling theory. As a result, the dynamic critical exponent is estimated to be Z = 2.94 * 0.29.

Ipso-amidation of arylboronic acids: Xenon difluoride-nitriles as efficient reagent systems

“…It is also known to be a powerful oxidizing agent [15,17,18]. So far, no XeF 2 -mediated amidation reactions have been reported.…”

“…[absorber (1)], and the band at ∼1748 cm -1 (marked with an asterisk in Figure 1) correlates with the 1478 cm -1 band [absorber (2)]. An additional species forming upon annealing is C 2 H 3 (891 cm -1 ), 16 showing reactions of H atoms with a residual H 2 C 2 precursor.…”

High coordination chemically bound compounds of noble gases with hydrocarbons: Ng(CCH)4 and Ng(CCH)6, (Ng=Xe or Kr)

“…[3][4][5][6][7] By far, most of these molecules contain fluorine atoms, the high electronegativity of which is crucial for the ionic bonding of these systems. [8][9][10][11][12] Some noble gas compounds were made also with strongly electronegative atoms, such as oxygen. [8][9][10][11][12] An important sub-family of these compounds are "organic-rare" molecules which involve Ng-C bonds and fluorinated groups.…”
