Bardin, V. V. published the artcileReaction of polyfluoroaromatic compounds with electrophilic agents in the presence of tris(dialkylamino)phosphine. I. Synthesis of trialkylsilyl(germyl, stannyl or plumbyl)polyfluorobenzenes, Formula: C9H9F5Si, the publication is Zhurnal Obshchei Khimii (1992), 62(10), 2342-9, database is CAplus.
In the presence of an equimolar amount of P(NEt2)3, polyfluorophenyl bromides react with alkylhalosilanes, -germanes, -stannanes, and -plumbanes to give the corresponding phenyl(alkyl) derivatives of these elements plus a phosphonium salt. Electron-donating groups in the 4-position of the polyfluorophenyl bromide slow the reaction, whereas electron-accepting groups accelerate it.
Zhurnal Obshchei Khimii published new progress about 1206-46-8. 1206-46-8 belongs to catalysis-chemistry, auxiliary class Organic Silicones, name is Trimethyl(perfluorophenyl)silane, and the molecular formula is C9H9F5Si, Formula: C9H9F5Si.
