Kashiwabara, Taigo published the artcileDecarbonylative Coupling of Fluorobenzoyl Chlorides with Hexamethyldisilane in the Presence of a Palladium Complex Catalyst: Extremely Facile Decarbonylation of Pentafluorobenzoyl-Pd Complex Relevant to C₆F₅SiMe₃ Formation, Application of Trimethyl(perfluorophenyl)silane, the publication is Organometallics (2006), 25(19), 4648-4652, database is CAplus.

Pd-phosphite complexes (PdCl₂(PhCN)₂ + P(OEt₃)₃ or P(OPr)₃ most effective) catalyze the reaction of pentafluorobenzoyl chloride with hexamethyldisilane to selectively form pentafluorophenyltrimethylsilane as virtually the sole product. The reaction of 3,5-difluoro- or 4-fluorobenzoyl chloride was less selective, giving a mixture of corresponding benzoyl- and phenylsilanes. Oxidative addition of pentafluorobenzoyl chloride with Pd(PPh₃)₄ or with Pd[P(OEt)₃]₂ generated in situ proceeds readily, but decarbonylation occurs, giving trans-C₆F₅PdClL₂ (L = PPh₃, P(OEt)₃), selectively. The crystal and mol. structures of trans-C₆F₅PdCl(PPh₃)₂ were determined by x-ray crystallog.

Saidalimu, Ibrayim published the artcileSuccessive C-C bond cleavage, fluorination, trifluoromethylthio- and pentafluorophenylthiolation under metal-free conditions to provide compounds with dual fluoro-functionalization, Recommanded Product: Trimethyl(perfluorophenyl)silane, the publication is Chemical Science (2016), 7(3), 2106-2110, database is CAplus and MEDLINE.

The selective C-C bond cleavage and simultaneous formation of two C-F bonds and one C-S bond in ¦Â-keto esters with nucleophilic fluorination reagents such as DAST under metal-free/catalyst-free conditions was disclosed. Double fluorination at two remote carbons with addnl. dialkylamino-sulfenylation provided unique fluorinated compounds in good to high yields. This method was applied for the successive C-C bond cleavage/fluorination/trifluoromethylthiolation of ¦Â-keto esters using trifluoromethyl-DAST (CF₃-DAST) providing different type of fluorinated and trifluoromethylthiolated compounds via a shunt pathway. Doubly fluoro-functionalized compounds obtained in these reactions were unique and difficult to synthesize by other methods.

Komoda, Kazuki published the artcileSolvent-Promoted Catalyst-Free Nucleophilic Fluoroalkylation of Aldehydes, Recommanded Product: Trimethyl(perfluorophenyl)silane, the publication is ChemistrySelect (2019), 4(8), 2374-2378, database is CAplus.

Fluoroalkyl silanes are useful building blocks for nucleophilic introduction of fluoroalkyl groups into organic mols. In general, fluoroalkyl silanes per se are stable compounds, but they are amenable to reactions as fluoroalkyl anion equivalent in the presence of base such as fluoride ion. Usually, KF acts as a good catalyst for nucleophilic fluoroalkylation of carbonyl compounds To avoid the use of hygroscopic fluoride salts, we have developed a convenient catalyst-free method for nucleophilic fluoroalkylation of aldehydes and ketones by the use of fluoroalkyl silanes. Trifluoromethyl(trimethyl)silane (Me₃Si-CF₃), and other fluoroalkyl silanes (Me₃Si-R_f) underwent solvent-promoted nucleophilic addition to aldehydes smoothly to give fluoroalkylated alcs. in good yields. In the present reactions, the use of polar solvents such as DMSO, DMF or NMP is essential to the formation of 1,2-adducts.

Huang, Dejian published the artcileCleavage of F-C(sp²) bonds by MHR(CO)(P^tBu₂Me)₂ (M = Os and Ru; R = H, CH₃ or Aryl): Product dependence on M and R, Product Details of C9H9F5Si, the publication is Polyhedron (2006), 25(2), 459-468, database is CAplus.

Both MH(Ph)(CO)L₂ (L = P^tBu₂Me; M = Ru and Os) react with vinyl fluoride to form M-F bonds; however, Ru eliminates benzene, while Os eliminates ethylene. In contrast, Ru(H)₂(CO)L₂ and Os(H)₂(CO)(1-butene)L₂ both react with vinyl fluoride to give ethylene and MHF(CO)L₂. Ethylene production from both dihydrides is attributed to ¦Â-F migration to M from an MCH₂CH₂F transient, while the unique behavior of RuH(Ph)(CO)L₂ (giving the C-F oxidative addition product Ru(¦Ç¹-vinyl)F(CO)L₂) is attributed to the difficulty of achieving Ru^IV, and the ability of the strongly ¦Ð-acidic vinyl fluoride to rapidly trigger reductive elimination of benzene. The products of reaction of RuH(Ar)(CO)L₂ with vinyl fluoride are redirected more towards ethylene formation when Ar carries fluorine substituents. The reaction products of OsH(R)(CO)L₂ with vinyl fluoride revert to R-H elimination when R is Me. Finally, the more ¦Ð-acidic H₂C:CF₂ triggers very rapid CH₄ elimination from OsH(CH₃)(CO)L₂; cleavage of the second C-F bond yields the vinylidene OsF₂(CCH₂)(CO)L₂. All selectivity is rationalized via the fate of the adduct MH(R)(C₂H_4-nF_n)(CO)L₂.
