  Electrophilic and nucleophilic side chain fluorination of para-substituted acetophenones

  摘要：

  para-Substituted alpha-fluoroacetophenones have been synthesised by three different routes. Electrophilic fluorination of trimethylsilyl enol ethers of acetophenones using Selectfluor (F-TEDA-BF4, 1-chloromethyl-4-fluoro- 1,4-diazoniabicyclo[ 2.2.2]octane bis-(tetrafluoroborate)) gave high to moderate yield depending on the electronic properties of the substituents. F-TEDA-BF4 mediated fluorination of acetophenones in methanol resulted in a mixture of alpha-fluoroacetophenones and the corresponding 2-fluoro- 1,1 -dimethyl acetals. The dimethyl acetals were hydrolysed using trifluoroacetic acid in water to maximise the yield of the product. Nucleophilic fluorination of alpha-bromoacetophenones using tetrabutylammoniurn hydrogen bifluoride (TBABF) led to moderate yield when having electron-donating substituents, whereas low yields were experienced when more electron-withdrawing substituents were introduced.

  P(III)/P(V) 催化酰氟、甲硅烷基烯醇醚和炔烃的三组分偶联

  摘要：

  我们在此报道了通过酰基氟、甲硅烷基烯醇醚和炔酸酯的三组分偶联的膦催化氢化乙烯基化反应。反应成功的关键是五配位 P(V) 物质（即氟代正膦）和甲硅烷基烯醇醚之间的形式转移金属化，这允许在极性不匹配的位点之间形成 C-C 键。即使通过过渡金属催化也无法实现的键形成是通过 P(III)/P(V) 歧管完成的。

  日期：2017.9.1

  An enantioselective NHC (N-heterocyclic carbene) catalyzed synthesis of indenes from bifunctional α,β-unsaturated acyl fluorides and TMS enol ethers has been discovered. The reaction has broad generality (31 examples) and proceeds with high levels of enantioselectivity (most >92:8 er). Mechanistically the reaction likely occurs via a Michael/β-lactonization/decarboxylation sequence. Derivatization

  bond formation reactions via acylnitrene transfer have recently attracted much attention, but direct detection of the proposed acylnitrenoid/acylimido M(NCOR) (R=aryl or alkyl) species in these reactions poses a formidable challenge. Herein, we report on Ru(NCOR) intermediates in C−N bond formation catalyzed by [RuIV(Por)Cl2]/N3COR, a catalytic method applicable to aziridine/oxazoline formation from

  通过酰基硝烯转移的金属催化的 CN 键形成反应最近引起了很多关注，但在这些反应中直接检测所提出的酰基硝烯/酰基酰亚胺 M(NCOR)（R = 芳基或烷基）物质是一项艰巨的挑战。在此，我们报告了由 [Ru IV (Por)Cl 2 ]/N 3 COR 催化形成 CN 键的 Ru(NCOR) 中间体，这是一种适用于从烯烃形成氮丙啶/恶唑啉、取代吲哚胺化、α -由甲硅烷基烯醇醚形成氨基酮，C(sp 3)−H 键，以及天然产物和碳水化合物衍生物的功能化（产率高达 99%）。实验研究，包括 HR-ESI-MS 和 EPR 测量，加上 DFT 计算，为 Ru(NCOR) 酰基硝烯类化合物作为 Ru V -imido 物种的配方提供了证据。

  A method for the synthesis of diversely substituted 3-fluoropyridines from two ketone components is described. The reaction involves photoredox coupling of α,α-difluoro-β-iodoketones with silyl enol ethers catalyzed by fac-Ir(ppy)3 under blue LED irradiation with subsequent one-pot condensation with ammonium acetate. Based on cyclic voltammetry studies, it was determined that α,α-difluoro-β-iodoketones
