    摘要:
    通过TMS-Cl消除途径,从氯亚胺盐和烷氧基硅烷中以高收率制备了一系列空间要求高的无环氨基氧化碳烯(AAOC)。通过Au(I)配合物的X射线晶体学研究确定了大体积AAOC的空间分布。埋入体积百分比值(%V BurAAOC配体的)范围从35.8%到47.9%。无环氨基氧卡宾在卡宾中心周围保持共面性,与同样庞大的无环二氨基卡宾显示出明显的共面畸变,这形成了鲜明的对比。AAOCs的Au(I)络合物在烯基脲的加氢胺化反应中显示出高效率。较大的AAOC–Au(I)配合物显示出更快的反应速率和更高的转化率。用AAOC-Au(I)催化剂观察到的反应速率,收率和立体选择性要好于无环二氨基卡宾Au催化剂,并且可与迄今为止报道的最佳结果相媲美。

  • 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

  • Evaluation of benzthiazolidine-based formamidinium salts for the synthesis of penem-type <i>β</i>-lactams by uncatalysed carbonylation of acyclic diaminocarbenes

    Abstract The reaction of [iPr2N=CHCl]Cl with 2-phenylbenzthiazolidine (Ph-BtzH) and subsequent anion metathesis afforded the formamidinium salt [(Ph-Btz)CH(NiPr2)][PF6] ([1aH][PF6]). The reaction of [1aH][PF6] with (Me3Si)2NNa in the presence of grey selenium furnished the selenourea derivative 1aSe as trapping product of the acyclic diaminocarbene 1a. In the absence of selenium, a 2H-1,4-benzothiazine
    摘要 [iPr2N=CHCl]Cl 与 2-苯基苯并噻唑烷 (Ph-BtzH) 和随后的阴离子复分解反应得到甲脒盐 [(Ph-Btz)CH(NiPr2)][PF6] ([1aH][PF6])。[1aH][PF6] 与 (Me3Si)2NNa 在灰色硒存在下的反应提供了硒脲衍生物 1aSe 作为无环二氨基卡宾 1a 的捕获产物。在没有硒的情况下,获得了 2H-1,4-苯并噻嗪衍生物 (2),它是 1a 的异构体,其形成似乎是由 [1aH]+ 的去质子化引发的,不是在阳离子 N2CH 单元,而是在相邻的 PhCH 位置。CO 作为 1a 的捕集剂无效。[1aH][PF6]、1aSe 和 2 已通过 X 射线衍射进行了结构表征。
  • N,N-Diisopropylformamidine (DIFA) Protection of Anilines in Metalation Reactions
    作者:Paul Zhichkin、Sergiy Krasutsky、Ravi Krishnamoorthy
    DOI:10.1055/s-0030-1259058
    日期:2010.12
    A novel N,N-diisopropylformamidine (DIFA) protecting group for anilines was studied. Metalation is often metal-directed by this weakly coordinating and bulky group, making it complementary to ortho-metalation directed by tert-butylcarbamate and pivaloylamide groups and to regular electrophilic reactions of anilines. Importantly, DIFA is removed under nucleophilic conditions and is stable toward acids, thus being orthogonal to tert-butylcarbamate, N-tert-butylamide, and other acid-labile protecting groups.
    研究了一种新型N,N-二异丙基甲酰胺保护基(DIFA)用于对苯胺。金属化过程常常受到这种弱配位且体积庞大的基团的金属导向,使其与由叔丁基碳酸酯和伐尔酰胺基团引导的邻位金属化相辅相成,并且与对苯胺的常规电亲反应兼容。重要的是,DIFA在亲核条件下可被去除,并且对酸稳定,因此与叔丁基碳酸酯、N-叔丁酰胺和其他酸敏感的保护基具有正交性。

    secondary carbene palladium(II) complexes (1b–3b) were synthesized via oxidative insertion of Pd2(dba)3 (dba = dibenzylideneacetone) into the C–Cl bond of dialkyl(chloromethylene)ammonium chloride salts ([R2NCHCl]+Cl−). All complexes have been characterized by 1H, 13C, and 31P NMR analysis. X-ray diffraction studies on single crystal of 3b confirm the cis square planar geometry. Complexes (1b–3b) have been

    The portfolio of acyclic diaminocarbenes (ADACs) has been substantially expanded, owing to the synthesis of eleven new formamidinium salts, mostly of the type [(iPr2N)CH(NRR′)][PF6], for use as immediate carbene precursors. The corresponding ADACs (iPr2N)C(NRR′) were sufficiently stable for isolation in the case of NRR′=2‐methylpiperidino (13), 3‐methylpiperidino (14), 4‐methylpiperidino (15), morpholino
