The conversion of bulky chlorosilanes to fluorosilanes under anhydrous conditions with hexafluorosilicate salts is accelerated by ultrasound. The fluorination of sterically hindered chlorosilanes such as ^tBuPh₂SiCl, in the absence of ultrasound, is greatly accelerated by the addition of H₂O to the reaction mixture

The copolymerization of ethylene and butadiene with a supported titanium catalyst (TiCl₄/MgCl₂/Et benzoate/Ph₂SiCl₂/AlEt₃) was described. The resulting products were characterized by IR, ¹³C NMR, x-ray diffraction, differential thermal anal., electron microscopy, and solvent extraction The butadiene units were substantially in trans-1,4-configuration and blocked sequences. Both ethylene and butadiene blocks formed crystalline phases. The presence of unsaturated bonds made it possible to graft Me methacrylate and maleic anhydride. The influences of monomer composition, temperature, Al/Ti ratio, catalyst concentration, and solvents on the copolymerization were investigated.

Li, Ren-Zhe published the artcileAsymmetric O-propargylation of secondary aliphatic alcohols, Safety of Difluorodiphenylsilane, the publication is Nature Catalysis (2020), 3(8), 672-680, database is CAplus.

Here, we report the development of a base-free, Cu-catalyzed propargylic substitution reaction that enables the efficient, asym. O-propargylation of secondary aliphatic alcs. Mechanistic studies implied key factors to slow down the undesired decomposition process of electrophiles in this reaction, which opened up the possibility of using secondary aliphatic alcs. as nucleophilic substrates. This asym. O-alkylation reaction proceeds under almost neutral conditions, tolerates a broad scope of functional groups and showed remarkable chemoselectivities. This method was amenable to the modification of natural products and com. drugs. The products obtained was readily elaborated to various classes of enantioenriched ¦Á,¦Á’-disubstituted ethers that were difficult to access by other methods.

Koritzer, Richard T. published the artcileEnhanced fluoride penetration and retention in enamel, Product Details of C12H10F2Si, the publication is Caries Research (1979), 13(5), 259-64, database is CAplus and MEDLINE.

Fluorosilanes enhanced the retention and improved the penetration of fluoride into enamel in vitro. The efficacy of this treatment seemed to lie in its ability to utilize the enamel organic network as a conduit to increase the enamel prism surface area accessible to reaction with fluoride. Thus, silanes may be effective as a vehicle to transport fluoride via the organic network to loci best suited for therapeutic effectiveness.

Compounds having a silole ring condensed with benzothiophene and N-methylindole units (BBTS and BMIS; shown as I and II) were prepared The electronic states of BBTS and BMIS were examined with respect to their UV and emission spectra and CV measurements, in comparison with those of bibenzothiophene and bi-N-methylindole, indicating that the existence of the silole ring in BBTS and BMIS affects the electronic states to decrease the HOMO-LUMO energy gaps. The results of MO calculations on model compounds agree well with the exptl. observations. The crystal and mol. structures of II were determined by x-ray crystallog. Electroluminescence devices based on I and II performed poorly.
