Chernyshev, E. A. published the artcileAddition of arylfluorosilanes to styrene, HPLC of Formula: 312-40-3, the publication is Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya (1965), 650-4, database is CAplus.

Addition of 16 g. 40% HF at -30 to -40¡ã to 60 g. PhSiHCl₂ gave 74% PhSiHF₂, b. 111-11.5¡ã, n²⁰_D 1.4442, d₂₀ 1.1194; similarly were prepared 55% Ph₂SiHF, b₂ 92-3¡ã, 1.5550, 1.1072, and 48% 1-C₁₀H₇SiHF₂, b₂₀ 124-6¡ã, 1.5600, 1.2136. PhSiHCl₂ added to PhCH:CH₂ in the presence of H₂PtCl₆ catalyst gave after 5 hrs. on a stream bath 43% PhCH₂CH₂SiPhF₂, b_2.5 134¡ã, 1.5650, 1.1688. PhCH:CH₂ and PhSiHF₂ similarly gave in 2 hrs. at 30-5¡ã 83% mixed PhC₂H₄SiPhF₂, b₂₀ 160-2¡ã, 1.5262, 1.1156; ir spectra indicated that the CHMe bridge predominated over the CH₂CH₂ bridge in this mixture by 3:1. PH₂SiHF and PhCH:CH₂ gave 80% 1:1 mixture of isomeric PhC₂H₄SiPh₂F, b_4.5 194.5-96¡ã, 1.5828, 1.1036. 1-C₁₀H₇SiHF₂ and PhCH:CH₂ gave 65% mixed isomers of 1-C₁₀H₇Si(C₂H₄Ph)F₂, b₂ 154-6¡ã, 1.5915, 1.1876. A 1:1 mixture of PhSiHF₂ and PhSiHCl₂ kept 1.5 hrs. then treated with PhCH:CH₂ and H₂PtCl₆ gave 83.8% PhC₂H₄SiPhF₂; other ArSiHF₂ behaved similarly. Passage of PhSiHF₂ and PhCl through a quartz tube at 580¡ã gave 22% Ph₂SiF₂, b₄ 98¡ã, 1.5372, 1.1554, and some PhSiF₃ and PhSiHF₂.
