    1H-1,2,4-diazaphospholes: Synthesis, structural characterization, and DFT calculation
    摘要:
    A few 1H-1,2,4-diazaphospholes H[3,5-R(2)dp] (R = methyl (5a), p-tolyl (5b), 1-naphthyl (5c), 2-furanyl (5d), 2-thienyl (5e), and isopropyl (5f)) were prepared and structurally characterized by a substantial experimental modification of the synthetic protocol. The molecules of all compounds are linked into oligomers via the bridges of NH ... N hydrogen bonds in solid state. The tetrameric feature of 5a, and 5d-f represents a new motif of hydrogen-bonded 1H-1,2,4-diazaphospholes in solid state. The OFT calculation at the B3LYP/6-311++G** level suggested the possible proton disorder with intermolecular solid state proton transfer (ISSPT) between 1H-1,2,4-diazaphosphole rings.

  • Frustrated Lewis Pair Catalyzed Hydrogenation of Amides: Halides as Active Lewis Base in the Metal-Free Hydrogen Activation
    作者:Nikolai A. Sitte、Markus Bursch、Stefan Grimme、Jan Paradies
    DOI:10.1021/jacs.8b12997
    日期:2019.1.9
    reductant is introduced. The reaction proceeds via the hydrogen splitting by B(2,6-F2-C6H3)3 in combination with chloride as the Lewis base. Density functional theory calculations support the unprecedented role of halides as active Lewis base components in the frustrated Lewis pair mediated hydrogen activation. The reaction displays broad substrate scope for tertiary benzoic acid amides and α-branched carboxamides

    日期:1966.1
    The reaction of N,N-dimethyl- or N,N-pentamethylene-formamide chlorides with n-butyl, cyclohexyl, and 2,4-xylyl isocyanides results in the formation of 1:2-adducts which are readily converted by water to N,N'-disubstituted α-(dialkylamino)malonamides. In the case of N,N-dimethylamide chlorides of acetic, propionic, and benzoic acids, the products are the corresponding N-substituted α-ketoamides resulting

    An experimentally simple and convenient synthesis of 4-susbstituted 2-(trichloromethyl)quinazolines by cycloaddition of benzyne with 2-(trichloromethyl)-1,3-diazabutadienes was developed. The 2-(trichloromethyl)-1,3-diazabutadienes (R1 = H and Me) were prepared from trichloroacetamidine and the appropriate N,N-dimethylamide dimethyl acetal or from trichloroacetamidine and a Vilsmeier–Haack reagent

  • Photo-on-Demand Synthesis of Vilsmeier Reagents with Chloroform and Their Applications to One-Pot Organic Syntheses
    作者:Fengying Liang、Kazuo Eda、Takashi Okazoe、Akihiro Wada、Nobuaki Mori、Katsuhiko Konishi、Akihiko Tsuda

    The Vilsmeier reagent (VR), first reported a century ago, is a versatile reagent in a variety of organic reactions. It is used extensively in formylation reactions. However, the synthesis of VR generally requires highly toxic and corrosive reagents such as POCl3, SOCl2, or COCl2. In this study, we found that VR is readily obtained from a CHCl3 solution containing N,N-dimethylformamide or N,N-dimethylacetamide
    Vilsmeier试剂(VR)于一个世纪前首次报道,是一种用于多种有机反应的多功能试剂。它被广泛用于甲酰化反应中。然而,VR的合成通常需要剧毒和腐蚀性试剂,例如POCl 3,SOCl 2或COCl 2。在这项研究中,我们发现在O 2鼓泡下进行光辐照后,VR很容易从含有N,N-二甲基甲酰胺或N,N-二甲基乙酰胺的CHCl 3溶液中获得。通过产生气态HCl和CO 2可以高收率获得相应的Vilsmeier试剂作为副产物,以使其分离为适合通过X射线晶体学分析的结晶固体产物。利用使用双功能充当反应物和溶剂的CHCl 3的优点,这种按需光敏VR合成可用于一锅合成醛,酰氯,甲酸酯,酮,酯和酰胺。
