  摘要：

  N-氟吡啶鎓盐提供了一种新的氟化剂系统，通过该系统，由于氟化能力的不同程度，反应性不同的各种亲核底物可以被氟化，并且还可以通过结构改变非常有选择性地氟化。在现有结果的基础上，选择性氟化的范围应该大大拓宽。因此，N-氟吡啶鎓盐系统应该可以制备许多有用的有机氟化合物

  N-Fluoropyridinium salts provide a new system of fluorinating agents by which a wide range of nucleophilic substrates differing in reactivity can be fluorinated due to the varying degree of fluorinating power and also fluorinated very selectively through structural alteration. The scope of selective fluorination should be broadened considerably on the basis of the present results. The N-fluoropyridinium

  N,N'-Difluoro-2,2'-, -2,4'-, -3,3'-, -4,4'-bipyridinium and substituted N,N'-difluoro-2,2'-bipyridinium bis(triflates), bis(tetrafluoroborates), bis(hexafluorophosphates), and bis(hexafluoroantimonates) 1-9 were synthesized in high yields by the direct fluorination of a mixture of a bipyridyl and a Lewis acid, a Bronsted acid, or the alkali metal salt of an acid. The higher homologues, trimer 10 and polymer II, were also synthesized. Unsubstituted or electron-donating group-substituted N,N'-difluorobipyridinium salts are stable nonhygroscopic crystals, while the electron-withdrawing group-substituted N,N'-diflurobipyridinium salts 3, 5, and 6 are moisture-sensitive crystals. Hydrolysis of Ib in boiling water gave 3,3'-dihydroxy-2,2'-bipyridyl. The reactivity determination indicated that the fluorinating capability decreased in the order 2,2'- much greater than 2,4' > 3,3'- approximate to 4,4'-isomer much greater than N-fluoropyridinium salt and that the two N-F moieties in a molecule mere effective for fluorination. This fluorination occurred in a step-by-step manner, and the reactivity difference between the first and second fluorinations was very small. N,N'-Difluoro-2,2'-bipyridinium bis(tetrafluoroborate) (Ib) is thus shown to be a highly reactive and easy-to-handle electrophilic fluorinating agent with the high effective fluorine content (103.3 g/kg) for preparing many fluoro organic compounds.

  N-Fluorobis(perfluoroalkyl)sulfonyl]imides are a new class of electrophilic fluorinating agents. Reaction of (CF3SO2)2NF (1) with olefins gave various products, depending on the reaction conditions and the structure of the substrate. In solvents of higher nucleophilicity such as H2O, acetic acid, aqueous HCl, and (HF)(n)Py, alpha-fluorohydrins or their acetates, alpha,beta-chlorofluoro- and alpha,beta-difluoroalkanes were obtained. In acetic acid, trans-stilbene and tetraphenylethylene produced the rearranged, nonfluorinated aldehyde and ketone. Evidence is presented for the reactions proceeding via a one-electron transfer mechanism involving alpha-fluorocarbocationic intermediates.

• Highly Selective Fluorinating Agents: a Counteranion-Bound N-Fluoropyridinium Salt System
  作者：Teruo Umemoto、Ginjiro Tomizawa

  A series of alkyl- or (trifluoromethyl)-substituted N-fluoropyridinium-2-sulfonates 2a-h, differing in fluorinating power, were synthesized, and assessment was made of the effectiveness of each selective fluorinating agent. N-Fluoropyridinium-3- and -4-sulfonates 3 and 4 were also synthesized. Power-variables 2a-h were found to be highly selective fluorinating agents for a wide range of nucleophilic substrates such as activated aromatics, enol trialkylsilyl and alkyl ethers, active methylene compounds, activated olefins, and sulfides. Thus, phenol, naphthol, phenylurethane, and the trimethylsilyl ether of phenol were exclusively or highly selectively fluorinated at the o-position with 2f-h. Conjugated enol trialkylsilyl ethers of a steroid were regioselectively fluorinated at the 6-position with moderately powerful 2b-e. This regioselectivity increased with the bulkiness of the silyl part, and with the most bulky triisopropylsilyl group exclusive B-fluorination was achieved. Preferential beta-stereoselective fluorination at the 6-position was observed. N-Fluoropyridinium-2-sulfonates were activated with an acid. This acid-catalyzed fluorination led to the preferential p-fluorination of anisole. The present results can be explained based on the capacity of the 2-sulfonate anion to interact with the hydroxy group of phenol or naphthol, NH group of phenylurethane, silicon atoms of silyl ethers, or protons of acids.
