The treatment of cesium salts of CB₁₁H₁₂^–, CB₉H₁₀^–, B₁₂H₂^–, and B₁₀H₁₀^2- with the com. available N-fluoro reagent 1-chloromethyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate) (F-TEDA) resulted in the formation of fluorinated derivatives of these 10- and 12-vertex borane and carborane anions. This is the first reported use of an N-fluoro reagent to fluorinate B-H bonds of any type. The effects of changing the solvent, temperature, and reagent stoichiometry were studied. The derivatives 1-B₁₀H₉F²-, 2-B₁₀H₉F^2-, and 1,10-B₁₀H₈F₂^2- are the first fluorinated derivatives of the parent B₁₀H₁₀^2- cluster. For the other three parent anions, reactions with F-TEDA resulted in a higher degree of fluorination than reactions with liquid anhydrous hydrogen fluoride (LAHF) at the same temperature However, F-TEDA was less regioselective than LAHF for B-H B-F transformations.

Baudequin, Christine published the artcileEnantioselective electrophilic fluorination: a study of the fluorine-transfer from achiral N-F reagents to cinchona alkaloids, Application In Synthesis of 107263-95-6, the publication is Journal of Fluorine Chemistry (2003), 122(2), 189-193, database is CAplus.

A transfer fluorination on cinchona alkaloids with the aid of achiral N-F fluorine-transfer reagents is described. Ten com. available reagents were evaluated. Selectfluors, Accufluor, N-fluorobenzenesulfonimide (NFSi), and N-fluoro-2,6-dichloropyridinium tetrafluoroborate are effective fluorine-transfer reagents. The N-fluoroammonium salts of cinchona alkaloids thus prepared were employed in the construction of stereogenic fluorinated carbon centers with enantioselectivity as high as 85%. Ionic liquids are effective “green” solvents for the development of this methodol.

Pd-catalyzed highly para-selective C-H arylation of monosubstituted arenes (including toluene) is developed for the first time using an F⁺ reagent as a bystanding oxidant.

Bockman, T. M. published the artcileTime-resolved spectroscopy and charge-transfer photochemistry of aromatic EDA complexes with X-pyridinium cations, COA of Formula: C6H5F4NO3S, the publication is Journal of the Chemical Society, Perkin Transactions 2: Physical Organic Chemistry (1972-1999) (1992), 1581-94, database is CAplus.

Direct photoexcitation of 1:1 aromatic EDA complexes with various N-substituted X-pyridinium cations (X = nitro, fluoro, methoxy and acetoxy) is achieved by the specific irradiation of their charge-transfer (CT) absorption bands. Time-resolved picosecond spectroscopy refers to charge-transfer activation by the identification of the aromatic cation radical as the initial transient (T₁) formed in a photoinduced electron-transfer together with the X-pyridinyl radical. The homolytic fragmentation of the latter varies with the X-substituent in the order X = NO₂ > F > AcO > CH₃O, and the addition of X^{â€?/sup> to the aromatic donors leads to a series of cyclohexadienyl adducts that are identified as longer-lived transients (T₂) by time-resolved (nanosecond/μs) spectroscopy. The phototransients T₁ and T₂ together account for the different types of aromatic product (resulting from ring substitution, side-chain substitution and dimerization) that are generated by steady-state CT photochem. of the aromatic EDA complexes with X-pyridinium cations.}

Sano, Tomoharu published the artcileSynthesis of N-(1-Nitropyren-6-yl and 8-yl)-2′-deoxyribonucleosides, HPLC of Formula: 107263-95-6, the publication is Chemical Research in Toxicology (1995), 8(5), 699-702, database is CAplus and MEDLINE.

A new type of 1-nitropyrene-DNA adduct via addition-elimination reaction was synthesized. Treatment of fluorinated 1-nitropyrene with 3′- and 5′-O-protected 2′-deoxyribonucleoside in DMSO at 140 °C afforded N-(1-nitropyren-6-yl or 8-yl)-2′-deoxyribonucleoside, I (R = H, R¹ = NO₂; R =NO₂, R¹ = H). These DNA adducts resulted from addition of the exocyclic amino group of deoxynucleosides to the fluorinated carbon of the fluoro-1-nitropyrene following elimination of fluoride anion. This is the first report that describes the 1-nitropyrene-DNA adducts in which aromatic ring moiety of 1-nitropyrene is covalently linked to the exocyclic amino group of the deoxyribonucleoside. From our findings, we suggest that the addition-elimination reaction may be responsible for the formation mechanism of the putative 1-nitropyrene-DNA adducts in vivo.
