Synthesis of fluoro(aryloxo)alkaline earth metal cages by C-F bond activation.
نویسندگان
چکیده
Treatment of Ca or Sr metal with Hg(C(6)F(5))(2) and 2,4,6-trimethylphenol (HOmes) in 1,2-dimethoxyethane (dme) at room temperature resulted in C-F bond activation, giving rise to the unique fluoro(aryloxo)alkaline earth cages [Ca(5)(mu(4)-F)(mu(3)-F)(4)(mu-Omes)(4)(Omes)(dme)(4)] 1 and [Sr(10)(mu(4)-F)(4)(mu(3)-F)(4)(mu-Omes)(12)(dme)(4)] 2, which can be viewed as arrested fluorite structures.

Treatment of an alkaline earth metal (Ca, Sr, Ba) with 2,4,6-trimethylphenol (HOmes) at elevated temperatures in the presence of mercury under solvent-free conditions, followed by extraction of the reaction mixture with 1,2-dimethoxyethane (dme), afforded dinuclear alkaline earth aryloxo complexes [Ae2(Omes)4(dme)4] (Ae = Ca 1, Sr 3, Ba 6). Extraction of the Ca metal and HOmes reaction mixture ...
متن کاملThe Stability and Properties of Mn+@ C26-2nBnNn(M= alkaline and earth alkaline metals; n=0, 3) Complexes for Synthesis Application
The structural and electronic properties of C24-2nBn Nn and M@ C24-2nBn Nn (M= alkaline and earth alkaline metals; n=3 and 6) molecules are studied using the Density Functional Theory (DFT). It was found that the most interaction is in M@ C24-2nBn Nn complexes (M=Be, Mg; n=3 and 6). The negative nucleus-independent chemical shifts confirm that C24-2nBn Nn (n=3 and 6) cages exhibit aromatic char...
متن کاملIdentifying the presence of a disulfide linkage in peptides by the selective elimination of hydrogen disulfide from collisionally activated alkali and alkaline earth metal complexes.
We report a new method for identifying disulfide linkages in peptides using mass spectrometry. This is accomplished by collisional activation of singly charged cationic alkali and alkaline earth metal complexes, which results in the highly selective elimination of hydrogen disulfide (H2S2). Complexes of peptides possessing disulfide bonds with sodium and alkaline earth metal are generated using...

Different Aluminum: alkaline earth metal atomic weight ratios effects on structure transformations in alanates nanopowders were studied. Changes in crystal structures from alane to alanates by increasing alkaline earth metals dopants in the mixture with slight changes in crystal structures from rhombohedral centered – trigonal (alane) to trigonal (magnesium alanate), and monoclinic (calcium ala...
