O-(Fluorodimethylsilyl)phenyllithium (1) was prepared by Br-Li exchange between o-C₆H₄(SiMe₂F)Br (2) and t-BuLi in Et₂O at -78¡ã. The electrophilic Si-F functionality in 1 is not attacked by the nucleophilic aryllithium moiety at that temperature ⁷Li, ¹⁹F, and ²⁹Si NMR analyses supported by DFT calculations suggested that the structure of 1 involves an intramol. coordination of the F substituent to the Li atom. Reactions of 1 with halosilanes produced unsym., Si-halogenated o-disilylbenzenes 4.

Kawachi, Atsushi published the artcileStructures of [(Amino)phenylsilyl]lithiums and Related Compounds in Solution and in the Solid State, Category: catalysis-chemistry, the publication is Journal of the American Chemical Society (2000), 122(9), 1919-1926, database is CAplus.

The solution structures of [bis(diethylamino)phenylsilyl]lithium (1), [(diethylamino)diphenylsilyl]lithium (2), and [(diethylamino)phenylmethylsilyl]lithium (3) were studied by ¹³C, ²⁹Si, ⁷Li, and ¹⁵N NMR spectroscopic experiments The ²⁹Si-⁷⁽⁶⁾Li coupling can be observed in each species at low temperature The coupling patterns indicate that these three species exist as monomers in THF. Using a ¹⁵N-enrichment technique, the ²⁹Si-¹⁵N couplings in 1 and 2 are observed Next, the solid-state structures of [(diphenylamino)diphenylsilyl]lithium ((Ph₂N)Ph₂Si-X; X = Li) (4) and its fluoro (X = F), stannyl (X = SnMe₃), and hydro (X = H) derivatives were revealed by crystallog. studies as well as by solid-state ²⁹Si NMR experiments In the solid state, 4 exists as a monomer solvated with three THF mols. arising from the reaction solvent. The electropos. substituent X, such as Li, causes the elongation of the Si-C and Si-N bonds, reduction of the sum of the C-Si-N (or C) angles, and a downfield shift of the ²⁹Si resonances.

Ho, Benedict Y. K. published the artcileFragmentation and rearrangement processes in the high resolution mass spectra of diphenylsilyl compounds, Related Products of catalysis-chemistry, the publication is Organic Mass Spectrometry (1975), 10(5), 361-9, database is CAplus.

High resolution mass spectra of Ph2SiR2 (R = H, F, Cl) and Ph2Si(OR1)2 (R1 = Et, Me, H) were recorded. Metastable defocusing experiments showed that, if R or OR1 can be readily lost stepwise, the relative abundance of the biphenyl radical ion (I) is small, whereas, if neutral Si species such as :SiR2, ¡¤SiR, or :Si(OR1)2 are readily eliminated, the relative abundance I is large. I originates from both odd- and even-electron ions.

Damrauer, Robert published the artcileSynthesis of fluorosilanes from chlorosilanes: the use of hexafluorosilicates, Name: Difluorodiphenylsilane, the publication is Organometallics (1988), 7(5), 1161-4, database is CAplus.

The conversion of chlorosilanes to fluorosilanes has been studied by using sodium and ammonium hexafluorosilicate. Of particular interest has been their efficiency in the conversion of highly hindered chlorosilanes like dimesityldichlorosilane and (Me₃C)₂SiCl₂. (NH₄)₂SiF₆ was superior reagent for these conversions, since its reactions are more easily worked up and give higher yields. In addition, (NH₄)₂SiF₆ does not affect the Si-H, Si-Si, or Si-O-Si linkages as do many reagents which bring about chlorosilane to fluorosilane conversions.

Kim, Jaeseung published the artcileSilanediol peptidomimetics. Evaluation of four diastereomeric ACE inhibitors, Formula: C12H10F2Si, the publication is Bioorganic & Medicinal Chemistry Letters (2004), 14(11), 2853-2856, database is CAplus and MEDLINE.

Four diastereomers, e.g., I [X = Si(OH)₂], of a Phe-Ala peptide mimic incorporating a central silanediol group have been individually prepared and tested as inhibitors of angiotensin-converting enzyme (ACE). Three of the silanediols exhibit levels of inhibition that are similar to those of corresponding ketones reported by Almquist. For the fourth diastereomer, with both stereogenic carbons inverted relative to the most active isomer I, the ketone gives the least enzyme inhibition whereas the silanediol shows a surprisingly low IC₅₀ value.

cf. C.A. 53, 2787a. Raman and infrared spectra of mols. of the type PhSiX₃, Ph₂SiX₂, and Ph₃SiX (X = H, F, Cl), and of Ph₂Si(OH)₂, Ph₃SiOH, (Ph₃Si)₂O, (Ph₂SiO)₃, and (Ph₂SiO)₄ were measured and are given in graphs and tabular summaries. In the assignment of the bands, the internal oscillations of the Ph groups are easily separable from the oscillations of the rest of the mol. structure, and the valency frequencies Si-X can be assigned without difficulty. The partially occurring increase of these frequencies to values above those for the respective bands in the respective Me and H derivatives is discussed theoretically. The apparatus and methods used were the same as described in the previous publications.
