Synthesis and complex investigation of potassium ammonium hexafluorozirconates: I. Synthesis and X-ray diffraction study of K2-x (NH4)xZrF6 (0 < x < 2) crystals

The synthesis and X-ray diffraction study of compounds K_2-x (NH₄)xZrF₆ (0 < x < 2) were carried out. In all crystals of mixed composition, potassium cations are isomorphously replaced by ammonium cations. The compounds with x < 0.5 are isostructural to K₂ZrF₆ and those with x > 1.5, to (NH₄)₂ZrF₆. At 0.5 < x < 1.5, the structures are built of linear polymeric chains formed by edge-sharing Zr dodecahedra. The distribution of potassium and ammonium cations over the cationic positions was considered.     

Straightforward one-pot synthesis of benzofuroxans from o-halonitrobenzenes in ionic liquids

Treatment of o-halonitrobenzenes with sodium azide in a [empyrr][BF4]/Bu4NBr/H2O system gives benzofuroxans in high yields, with the recovery and reuse of the ionic liquid for at least ten times.     

Pluriharmonic Clark measures and analogs of model spaces

Let $B_d$ denote the unit ball of ${\mathbb{C}}^d$, $d\ge 1$. Given an inner function $I:B_d\to B_1$, we study the corresponding family ${\sigma }_{\alpha }[I]$, $\alpha \in ?B_1$, of pluriharmonic Clark measures on the complex sphere. We introduce and investigate related unitary operators $U_{\alpha }$ mapping analogs of model spaces onto $L^2({\sigma }_{\alpha })$, $\alpha \in ?B_1$. In particular, we explicitly characterize the set of $U_{\alpha }^{?}f$ such that $f{\sigma }_{\alpha }$ is a pluriharmonic measure.     

4,6-Dinitrobenzo[c]isothiazole: synthesis and 1,3-dipolar cycloaddition to azomethine ylide

1,3-Dipolar cycloaddition of 4,6-dinitrobenzo[c]isothiazole to (N-methyl-N-methylideneammonio)methanide (2 equiv.) gives 5,8-dimethyl-3b,6b-dinitrodecahydroisothiazolo[3,4-e]pyrrolo[3,4-g]isoindole, whose structure was confirmed by X-ray diffraction analysis.
