The reaction of diarylalkylsilanes and -germanes with trityl cation in the presence a weakly coordinating anion to give corresponding triarylsilylium or -germylium ions was investigated. This provides facile access larger range these sterically highly hindered Lewis acids. factors that promote substituent exchange were studied, significant effects substituent, solvent, group 14 element revealed. A combined solid-state XRD NMR investigation tris(pentamethylphenyl) silylium borate...
We report a strategy for preserving the structural features of collagen triple helix in turbostratic graphite.
The behavior of cellulose in molten salt hydrates, e. g., LiClO4*3 H2O, ZnCl2*4 LiCl*5 H2O and mixtures thiocyanates was investigated. Melts, which give rise to a swelling or dissolution the were focus interest. melt composition species, water amount structure coordination sphere cation hydrate as well acidity influence solubility systems. interactions between species melts determined by solution state 13C NMR measurements at temperatures 65°C 140°C. Each regenerated showed other but...
Caught by the octopus: The first structurally characterized metallasilatranes exhibit strong, formally dative Pd→Si and Pt→Si bonds (see picture; C gray, N blue, Si red, S yellow, Cl green, Pt black). atoms are hexacoordinate, transition-metal (TM) atom is a lone-pair donor. Short TMSi separations, pronounced upfield 29Si NMR signals, strong Si–Pt coupling show interaction between TM main-group element with an octet shell. Detailed facts of importance to specialist readers published as...
SO what? Spectral features caused by relativistic effects on chemical shift tensors are not always looked for in solid-state NMR spectroscopy. Slow-rotation 29Si magic-angle spinning (MAS) measurements the triad [ClTM(μ-mt)4SiCl] (TM=Pt, Pd, Ni; mt=2-mercapto-1-methylimidazolide) reveal that heavy-atom spin–orbit (SO) coupling has a dramatic impact spectral peak shape. Detailed facts of importance to specialist readers published as "Supporting Information". Such documents peer-reviewed, but...
Stable solid adducts of substituted pyridines (Rpy) with HSiCl(3) and HSiCl(2)Me were prepared in high yields under aprotic anaerobic conditions at room temperature. The octahedral complexes underwent dismutation reactions polar solvents. In contrast, the HSiCl(2)Me(Rpy)(2) not susceptible to comparable conditions, but they tended dissociate more easily because reduced Lewis acidity relative HSiCl(3). bonding between silicon its surrounding ligands is highly ionic, as can be seen from QTAIM...
Abstract New members of a novel class metallasilatrane complexes [X‐Si‐(μ‐mt) 4 ‐M‐Y], with M=Ni, Pd, Pt, X=F, Cl, Y=Cl, Br, I, and mt=2‐mercapto‐1‐methylimidazolide, have been synthesized characterized structurally by X‐ray diffraction 29 Si solid‐state NMR. Spin‐orbit (SO) effects on the chemical shifts induced metal, sulfur atoms in ligand, heavy halide ligands I were investigated help relativistic density functional calculations. Operators used calculations constructed such that SO...
Pushmi-pullyu with palladium: Although created by σ donation from SnCl2 to a PdII complex, the SnPd bonds in compounds depicted exhibit formal opposite direction. Computational and spectroscopic data support stannylpalladium (PdISnIII) palladastanna(IV)ocane (Pd0→SnIV) descriptions over stannylene coordination.
The lithium conductivity of NASICON glass-ceramic electrolytes can be increased 5 times just by using additives, which change the glass crystallization patterns.
Chitin, as a fundamental polysaccharide in invertebrate skeletons, continues to be actively investigated, especially with respect new sources and the development of effective methods for its extraction. Recent attention has been focused on marine crustaceans sponges; however, potential spiders (order Araneae) an alternative source tubular chitin overlooked. In this work, we our from up 12 cm-large Theraphosidae spiders, popularly known tarantulas or bird-eating spiders. These organisms...
Stable in the solid state and isolable high yields are adducts of H(2)SiCl(2), HSiCl(3), RSiCl(3) (R = Me, Ph) with N,N'-chelating ligands 1,10-phenanthroline (phen; 1c), 2,2'-bipyridine (bipy; 1b), (to a limited extent) N,N,N',N'-tetramethylethylenediamine (tmeda; 1a). The products were comprehensively characterized via multinuclear solution solid-state NMR spectroscopy, including analysis (29)Si chemical shift anisotropy tensors, Raman elemental analyses, and, for SiCl(4)(phen) (2c),...
