The conditions for the photocatalytic reductive alkylation of highly fluorinated arenes with ubiquitous and unactivated alkenes has been disclosed. The mild reaction conditions provide for a broad functional group scope, and the reaction is remarkably efficient using just 0.25 mol% catalyst. Finally, the utility of the strategy by converting highly fluorinated arenes to elaborate (hetero)arenes that contain 2-5 Caryl-F bonds via synergistic use of photocatalysis and SNAr chem was demonstrated.

The article was 《Photocatalytic C-F Bond Borylation of Polyfluoroarenes with NHC-boranes》. The article mentions the following:

The first photoredox-catalyzed defluoroborylation of polyfluoroarenes with NHC-BH3 has been facilely achieved at room temperature via a single-electron-transfer (SET)/radical addition pathway. This new strategy makes full use of the advantage of photoredox catalysis to generate the key boryl radical via direct activation of a B-H bond. Good functional group tolerance and high regioselectivity offer this protocol incomparable advantages in preparing a wide array of valuable polyfluoroarylboron compounds Moreover, both computational and exptl. studies were performed to illustrate the reaction mechanism.

In 2014,Scientific Reports included an article by Wu, Wenbo; Wang, Can; Li, Qianqian; Ye, Cheng; Qin, Jingui; Li, Zhen. Electric Literature of C9H5F5O2. The article was titled 《The influence of pentafluorophenyl groups on the nonlinear optical (NLO) performance of high generation dendrons and dendrimers》. The information in the text is summarized as follows:

With the aim to make the influence of pentafluorophenyl groups in the periphery of high generation dendrons and dendrimers on their NLO performance clearly, some NLO dendrons and dendrimers with different chromophore moieties or different end-capped groups were carefully designed and investigated in detail. The results demonstrated that some strong Ar-ArF interactions between the pentafluorophenyl groups in the periphery and the normal Ph rings of the donors, could influence the topol. structures of dendrons or dendrimers, and then affect their NLO performance. Furthermore, the optical transparency and the stability of the dendrons and dendrimers with pentafluorophenyl groups as end-capped moieties were all improved, in comparison with normal dendrons and dendrimers containing Ph ones as the end-capped groups. After reading the article, we found that the author used Ethyl 2,3,4,5,6-pentafluorobenzoate(cas: 4522-93-4Electric Literature of C9H5F5O2)

Product Details of 4522-93-4On March 7, 2016, Hu, Ji-Yun; Zhang, Jing; Wang, Gao-Xiang; Sun, Hao-Ling; Zhang, Jun-Long published an article in Inorganic Chemistry. The article was 《Constructing a Catalytic Cycle for C-F to C-X (X = O, S, N) Bond Transformation Based on Gold-Mediated Ligand Nucleophilic Attack》. The article mentions the following:

A tricoordinated gold(I) chloride complex, tBuXantphosAuCl, supported by a sterically bulky 9,9-dimethyl-4,5-bis(di-tert-butylphosphino)xanthene ligand (tBuXantphos) was synthesized. This complex features a remarkably longer Au-Cl bond length [2.632(1) Å] than bicoordinated linear gold complexes (2.27-2.30 Å) and tricoordinated XantphosAuCl [2.462(1) Å]. Single-crystal x-ray diffraction anal. of a cocrystal of tBuXantphosAuCl and pentafluoronitrobenzene (PFNB) and UV-visible spectroscopic titration experiments revealed the existence of an anion-π interaction between the Cl anion ligand and PFNB. Stoichiometric reaction between PFNB and tBuXantphosAuOtBu, after replacement of Cl by a more nucleophilic tBuO anion ligand, showed higher reactivity and para selectivity in the transformation of C-F to C-OtBu bond, distinctively different from that when only KOtBu was used (ortho selectivity) under the identical condition. Mechanistic studies including d. functional theory calculations suggested a gold-mediated nucleophilic ligand attack of the C-F bond pathway via an SNAr process. On the basis of these results, using trimethylsilyl derivatives TMS-X (X = OMe, SEt, NEt2) as the nucleophilic ligand source and the fluorine acceptor, catalytic transformation of the C-F bond of aromatic substrates to the C-X (X = O, S, N) bond was achieved with tBuXantphosAuCl as the catalyst (up to 20 turnover numbers). In the experiment, the researchers used many compounds, for example, Ethyl 2,3,4,5,6-pentafluorobenzoate(cas: 4522-93-4Product Details of 4522-93-4)
