In this study, preparation and decomposition of five novel pentavalent fluorosiliconates, RSi(CH3)3F- (R = CH3CH2O, CF3CH2O, (CH3)2CHO, (CH3)3SiO, and (CH3)3SiNH) is used to investigate the process of fluoride-induced desilylation. The siliconates were characterized by collision-induced dissociation and energy-resolved mass spectrometry....

A flow-through system is described for rapid purification of [18F]fluoride for nucleophilic substitution reactions. It depends on generation of [18F]fluorotrimethylsilane from aqueous 18F solutions and subsequent collection of the gas and its hydrolysis by base in near anhydrous acetonitrile. Potassium...
L Gámiz-Gracia et al.
Journal of pharmaceutical and biomedical analysis, 22(6), 909-913 (2000-06-17)
A selective dynamic method for the determination of fluoride in pharmaceuticals based on the integration of pervaporation and potentiometric detection in a laboratory-made module is proposed. The analyte was continuously converted into volatile trimetylfluorosilane by reaction with hexamethyldisilazane, injected into...

Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 62(4-5), 1058-1069 (2005-06-22)
The joint experimental and theoretical study of the vibrational spectra of the molecular series (CH3)3SiX (with X=H, F and Br) is carried out. Data from newly recorded IR and Raman spectra for the bromo derivative, experimental data obtained previously for...

The International journal of applied radiation and isotopes, 36(5), 375-378 (1985-05-01)
18F-Labeled fluorotrimethylsilane was prepared by nucleophilic substitution of chlorotrimethylsilane with reactor produced [18F]fluoride. Hydrolysis of fluorotrimethylsilane by aqueous tetraethylammonium hydroxide followed by removal of water with a mechanical pump gave a powerful source of no carrier added nucleophilic 18F. Reaction...

The International journal of applied radiation and isotopes, 36(4), 318-319 (1985-04-01)
[18F]Fluorotrimethylsilane was prepared in 80% decay corrected yield by reaction of no-carrier added tetramethyl-ammonium fluoride (hydroxide as bulk anion) with chlorotrimethylsilane in 65% aqueous acetonitrile. The 18F gas was collected in a cold-trap at -130 degrees C and found to...

The conventional procedure for separation of fluoride as trimethylfluorosilane in Conway diffusion cells involves the use of grease for sealing the cell and also for closing the hole in the lid drilled for introduction of hexamethyldisiloxane. We have developed a...
