Au-Catalyzed Synthesis of 5,6-Dihydro-8<i>H</i>-indolizin-7-ones from <i>N</i>-(Pent-2-en-4-ynyl)-β-lactams

Au-catalyzed synthesis of 5,6-dihydro-8H-indolizin-7-ones from readily available N-(pent-2-en-4-ynyl)-β-lactams is developed. In this reaction, a 5-exo-dig cyclization of the β-lactam nitrogen to the Au-activated C−C triple bond is followed by heterolytic fragmentation of the amide bond, forming a highly nucleophilic acyl cation. An expedient formal synthesis of indolizidine 167B was easily achieved using this new method

Designing an Air-Stable Interphase on Lithium Metal Anode to Improve Cycling Performance

The application of rechargeable lithium metal batteries is challenged by intractable issues of uncontrollable Li dendrite growth that result in poor cycle life and safety risks. In this work, an air-stable interphase is developed to protect the lithium metal anode (LMA) via a facile solution-based approach. The Ag-embedded fluoride-rich interphase not only creates abundant lithiophilic sites for homogenizing Li nucleation and growth but also resists severe air erosion to protect the LMA beneath and enable decent cycling stability. As a result, the Ag–F-rich interphase enables flat Li deposition on LMA, which is clearly observed in the operando Li plating experiments. Paired with a LiFePO4 cathode (11.8 mg cm–2), the Ag–F-rich interphase-modified LMA enables 300 stable cycles at 0.5 C, delivering a capacity retention ratio as high as 91.4%. Even after being exposed to air for 1 h, the modified LMA still runs smoothly for over 120 cycles with ignorable capacity decay, exhibiting great air stability. This work proves the concept of functionalizing the interphase on the LMA to enable good cycling performance even under severe air erosion

Gold-Catalyzed Efficient Preparation of Linear α-Iodoenones from Propargylic Acetates

Only 2 mol % of Au(PPh3)NTf2 is needed to convert readily accessible propargylic acetates into versatile linear α-iodoenones in good to excellent yields. This reaction is easy to execute and has broad substrate scope. Good to excellent Z-selectivities are observed in the cases of aliphatic propargylic acetates derived from aldehydes

For different samples, the left micrographs are bright-field TEM images obtained when the zone axis of olivine parallel to the electron beam, and the right micrographs are bright-field TEM images under two-beam conditions of the same area as in the left. (a) Bright-field TEM image viewed down [001] zone axis of olivine from sample B98. (b) Bright-field TEM image with a diffraction vector g=110, and the dislocations with Burgers vector b=001 become out of diffraction contrast. (c) Bright-field TEM image viewed down [001] zone axis of olivine from sample B106. (d) Bright-field TEM image with a diffraction vector g=200, and the dislocations with Burgers vector b=001 become out of diffraction contrast. (e–t) The same as above (the zone axis can be deduced from the selected area electron diffraction pattern which normal to the pattern, and the Burgers vector of the extinction dislocation can be calculated using g ∙ b = 0 and g ∙ (b Ʌu) = 0 criteria)
