Spialter, Leonard published the artcileNovel synthesis of organotri- and difluorosilanes with aqueous hydrofluoric acid, COA of Formula: C12H10F2Si, the publication is Tetrahedron Letters (1960), 11-14, database is CAplus.
In the presence of excess concentrated aqueous HF no hydrolysis products of halosilanes were isolated. Freshly distilled EtSiCl3 (25.0 g., b745 96.5¡ã) and 95 g. 48% HF shaken 1 hr. at 0¡ã in a polyethylene bottle and the evolved gases trapped at -78.5¡ã (solid CO2) yielded 88-90% EtSiF3, b. -5¡ã, d-76.5 1.227. Similarly, 26.4 g. PhSiCl3 (b737 197-9¡ã) and 78.0 g. 48% HF shaken vigorously 2 hrs. at 0¡ã and the washed (H2O) and dried (anhydrous Na2SO4) solution treated with NaF (to adsorb excess HF) yielded 85% PhSiF3, b737 98-104¡ã, n22D 1.4103. PhSiCl3 (52.8 g.) with 156 g. 48% HF in 200 ml. C5H12 shaken at 0¡ã with 50.0 g. 48% HF gave 43.5 g. Ph2SiF2, b737 260-5¡ã, n25D 1.5536. Under similar conditions (Ph3Si)2O was not cleaved to Ph3SiF, suggesting that siloxane formation may not take place prior to establishment of the Si-F bond and that either direct halogen substitution or interaction with the initial hydrolytic products of the chlorosilane may be steps in the mechanism.
Tetrahedron Letters published new progress about 312-40-3. 312-40-3 belongs to catalysis-chemistry, auxiliary class Organic Silicones, name is Difluorodiphenylsilane, and the molecular formula is C6H8O6, COA of Formula: C12H10F2Si.
