The temperature dependence of chem. shifts in o-(Me₂NCH₂)C₆H₄SiRR¹R² (I; R, R¹, R² = Me, Ph, 1-C₁₀H₇, H, F, Cl, OMe, OEt) and PhSiRR¹R² indicated the existence of an equilibrium between tetra- and penta-coordinate forms. I (R = 1-C₁₀H₇, R¹ = R² = H) is the 1st Si derivative without halogen or chalcogen to show intramol. pentacoordination. This coordination may account for the reactivity of the Si-H bond in this compound

Remarkable Difference in Reactivity between Diorganodichlorosilanes and Diorganodifluorosilanes, Computed Properties of 312-40-3, the publication is Organometallics (1995), 14(5), 2136-8, database is CAplus.

The [CH₂C(O)CPh₂]^2- dianion reacted with R₂SiCl₂ (R = Ph, CH₃, Et) to give cyclic products I but with R₂SiF₂ cyclic products II (R = Ph, Et) were formed. The structures of I and II (R = Ph) were determined by single-crystal x-ray diffraction. A reason for the difference in the regioselectivity of the reactions of the dianion with R₂SiCl₂ and R₂SiF₂ is suggested.

Seyferth, Dietmar published the artcileReactions of the 1,1-Diphenylacetone-Derived Dianion as a C,O-Dinucleophile with Organohalosilanes and -germanes, COA of Formula: C12H10F2Si, the publication is Organometallics (1997), 16(11), 2413-2426, database is CAplus.

1,1-Diphenylacetone dianion reacts with diorganodichlorosilanes to give 1,1,5,5-tetraorgano-3,7-bis(diphenylmethylene)-1,5-disila-2,8-dioxacyclooctanes, while 1,1-diphenylacetone dianion reacts with diorganodifluorosilanes to give a positional isomer, 1,1,5,5-tetraorgano-3,7-bis(diphenylmethylene)-1,5-disila-2,6-dioxacyclooctane. The structures of 1,1,5,5-tetraphenyl-3,7-bis(diphenylmethylene)-1,5-disila-2,8-dioxyacyclooctane and 1,1,5,5-tetraphenyl-3,7-bis(diphenylmethylene)-1,5-disila-2,6-dioxacyclooctane were determined by x-ray crystallog. A 10-membered cyclic compound and a 6-membered cyclic compound also were prepared by the reaction of 1,1-diphenylacetone dianion with 1,2-dichlorotetramethyldisilane and 1,3-dichlorohexamethyltrisilane, resp. The structure of 1,1,2,2,6,6,7,7-octamethyl-4,9-bis(diphenylmethylene)-1,2,6,7-tetrasila-3,10-dioxacyclodecane was determined by x-ray crystallog. 1,1-Diphenylacetone dianion reacts with diphenyldichlorogermane and diphenyldifluorogermane to give 1,1,5,5-tetraphenyl-3,7-bis(diphenylmethylene)-1,5-digerma-2,6-dioxacyclooctane. The structure of 1,1,5,5-tetraphenyl-3,7-bis(diphenylmethylene)-1,5-digerma-2,6-dioxacyclooctane was determined by x-ray crystallog. A possible explanation for the difference in the reactions observed with Ph₂SiCl₂ and Ph₂SiF₂ is presented. Experiments involving reactions of the 1,1-diphenylacetone dianion with monochlorosilanes indicate that a Si-CH₂, not an Si-O, bond is formed first.

Talavera, Maria published the artcileC-H and C-F Bond Activation Reactions of Fluorinated Propenes at Rhodium: Distinctive Reactivity of the Refrigerant HFO-1234yf, Recommanded Product: Difluorodiphenylsilane, the publication is Angewandte Chemie, International Edition (2019), 58(31), 10688-10692, database is CAplus and MEDLINE.

The reaction of [Rh(H)(PEt₃)₃] (1) with the refrigerant HFO-1234yf (2,3,3,3-tetrafluoropropene) affords an efficient route to obtain [Rh(F)(PEt₃)₃] (3) by C-F bond activation. Catalytic hydrodefluorinations were achieved in the presence of the silane HSiPh₃. In the presence of a fluorosilane, 3 provides a C-H bond activation followed by a 1,2-fluorine shift to produce [Rh{(E)-C(CF₃):CHF}(PEt₃)₃] (4). Similar rearrangements of HFO-1234yf were observed at [Rh(E)(PEt₃)₃] [E = Bpin (6), C₇D₇ (8), Me (9)]. The ability to favor C-H bond activation using 3 and fluorosilane is also demonstrated with 3,3,3-trifluoropropene. Studies are supported by DFT calculations

The nD and deviations of calculated nD as a function of concentration in MeCN were observed for R3SiX (where X = F or Cl and R = Me, Et, Ph, p-MeC6H4 or p-ClC6H4). Ir spectra of such systems were described and evidence of acid-base interaction was found for the fluoro- and chlorosilanes in which Si atoms are sp3d2-hybridized. Solid adducts Ph3SiF.2MeCN and Ph2SiF2.4MeCN were isolated.

A novel method toward a facile synthesis of diverse benzofuran derivatives I [R = Me, Et, Ph, etc.; R¹ = Me, Et] from easily obtained quinols and alkynyl esters was reported. A gold-catalyzed intermol. alkoxylation/Claisen rearrangement/condensation cascade was involved. The introduction of difluorodiphenylsilane as a water-trapping reagent in the reaction led to a higher yield.

The reaction of hydrosilanes, e.g., Ph₃SiH, with Cu^IIF₂¡¤2H₂O in refluxing CCl₄ gave the corresponding fluorosilanes, e.g., Ph₃SiF, in good yields. In THF hydrosilanes were recovered unchanged. X-ray powder anal. of the solid products indicated the formation of Cu^ICl. Probably both CCl₄ and Cu^II act as oxidants for hydrosilanes.

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, n²²_D 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, n²⁵_D 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.

Alkali metal salts of perfluorinated complex anions, e.g., NaPF₆, were used to effect halogen-exchange fluorination in organohalosilanes, e.g., Ph₃SiCl, both in the presence and absence of solvent. Using salts of perfluorinated nonnucleophilic anions in a high-boiling multifunctional etheral solvent, organofluorosilanes, e.g., Ph₃SiF, were conveniently prepared in high yields.
