    Visible-Light-Activated Enantioselective Perfluoroalkylation with a Chiral Iridium Photoredox Catalyst
    摘要:
    A visible-light-activated enantioselective radical perfluoroalkylation of 2-acyl imidazoles with perfluoroalkyl iodides (CF3I, C3F7I, C4F9I, C6F13I, C8F17I and C10F21I) and perfluorobenzyl iodide at the -position of the carbonyl group is reported. Enantioselectivities with up to >99.5% ee are achieved. The process uses a dual-function chiral Lewis acid/photoredox catalyst at loadings of 2-4mol% and constitutes a redox-neutral, electron-catalyzed reaction that proceeds via intermediate perfluoroalkyl radicals.

    coupling of oxazolines and N-heterocyclic carbenes leads to chelating C,N ancillary ligands for asymmetric catalysis that combine both an "anchor" unit and a stereodirecting element. Reacting various N-substituted imidazoles with 2-bromo-4(S)-tert-butyl- and 2-bromo-4(S)-isopropyloxazoline gave the imidazolium precursors of the stereodirecting ancillary ligands.

    Two copper Schiff base complexes, in both homogeneous and heterogeneous forms, were prepared and characterized by using elemental analysis, FTIR, UV–Vis spectroscopy and scanning electron microscopy. The catalytic performances of these complexes were studied in the N-arylation of N–H heterocycles with arylboronic acids in methanol without any added base at 40 °C under open air. The effects of various parameters such as solvent and temperature on the reaction system were studied. The reaction is applicable to a wide variety of N–H heterocycles and arylboronic acids. The heterogeneous catalyst was recovered by simple filtration, and reusability experiments showed that this catalyst can be used five times without much loss in the catalytic activity.

  • A Rhodium Catalyst Superior to Iridium Congeners for Enantioselective Radical Amination Activated by Visible Light
    作者:Xiaodong Shen、Klaus Harms、Michael Marsch、Eric Meggers
    DOI:10.1002/chem.201601572
    日期:2016.6.27
    catalysts reported before were unsuccessful in this enantioselective radical C−N bond formation. The surprising preference for rhodium over iridium is attributed to much faster ligand‐exchange kinetics of the rhodium complexes involved in the catalytic cycle, which is crucial to keep pace with the highly reactive and thus short‐lived nitrogen‐centered radical intermediate.
    双环属化(III)络合物可催化可见光活化的2酰基咪唑对映体选择性α-胺化反应,产率高达99%,ee高达98%。催化剂被赋予了双重功能,即手性路易斯酸,同时又是通过中间基自由基进行自由基链反应的光活化智能引发剂。值得注意的是,以前报道的相关基光氧化还原催化剂在这种对映选择性自由基CN键形成中没有成功。优于的出人意料的偏好归因于参与催化循环的配合物的配体交换动力学快得多,这对于跟上高反应性且因此寿命短的以氮为中心的自由基中间体至关重要。

    Abstract 3-(Diphenylphosphino)propanoic acid ( L2 ) has proved to be an efficient ligand for the copper-catalyzed C N coupling reactions. N -arylation of imidazoles with aryl iodides catalyzed by CuCl/ L2 was smoothly carried out in DMSO at 100 °C with a yield up to 98%.

    and indoles, with aryl and heteroaryl halides catalyzed by copper(I) oxide (Cu 2 O) nanoparticles is demonstrated. Four types of Cu 2 O were evaluated: the bulky compound and its cubic, octahedral, and spherical nanoparticulate forms. The results show that Cu 2 O nanoparticles, in particular the cubic form, are highly efficient for the N-arylation reaction. In the presence of cubic Cu 2 O nanoparticles
