  • Real-time monitoring of tritium gas reactions using Raman spectroscopy
    作者:J. Richard Heys、Mark E. Powell、Don E. Pivonka
    DOI:10.1002/jlcr.887
    日期:2004.11
    The utility of Raman spectroscopy for noninvasive, real-time monitoring of a range of tritium gas labeling reactions has been investigated, using deuterium gas as a model in most cases. Reaction types include organoiridium-catalyzed heteroatom-directed exchange (HDE), olefin hydrogenation and catalytic aryl dehalogenation. Five examples of HDE reactions with several different substrate types were monitored by observation of Raman vibrational bands sensitive to the isotopic substitutions. Changes in peak intensities and/or frequencies associated with the course of labeling are clearly observable at concentrations and reaction scales typical of tritium gas reactions. Similarly, Raman bands sensitive to the chemical changes that occur during catalytic deuterogenation of an olefin and to catalytic deuterium–bromine exchange of an aryl bromide were successfully monitored. This methodology can provide unprecedented real-time information, otherwise difficult to obtain, over the course of such reactions. Copyright © 2004 John Wiley & Sons, Ltd.
    通过在大多数情况下以氘气作为模型,研究了拉曼光谱在非侵入性、实时监测一系列氚气标记反应中的应用。反应类型包括有机铱催化的杂原子导向交换(HDE)、烯烃加氢和催化芳基脱卤。通过观察对同位素取代敏感的拉曼振动谱带,监测了五种不同底物类型的HDE反应。在典型的氚气反应浓度和反应规模下,可以清晰地观察到与标记过程相关的峰强度和/或频率的变化。同样,成功监测了对烯烃催化氘化过程中化学变化敏感的拉曼谱带,以及对芳基溴化物催化氘-溴交换过程中化学变化敏感的拉曼谱带。这种方法能够在这些反应过程中提供前所未有的实时信息,否则这些信息是难以获得的。版权所有 © 2004 John Wiley & Sons, Ltd。
  • Sequential Elimination-Reduction Reactions Promoted by Samarium Diiodide: Synthesis of 2,3-Dideuterioesters or -amides
    作者:José M. Concellón、Humberto Rodríguez-Solla
    DOI:10.1002/1521-3765(20011001)7:19<4266::aid-chem4266>3.0.co;2-8
    日期:2001.10.1
    A facile and general sequential elimination/reduction process promoted by samarium diiodide provides an efficient method for synthesizing saturated esters or amides 3 from readily available starting materials. The reaction involves a beta-elimination of the starting 2-halo-3-hydroxyesters or -amides 1 and subsequent 1,4-reduction of the obtained alpha,beta-unsaturated esters or amides in the presence
    由二碘化promote促进的简便且通用的顺序消除/还原过程提供了一种从容易获得的起始原料合成饱和酯或酰胺3的有效方法。该反应包括在存在H 2 O的情况下β-消除起始的2-卤代3-羟基酯或-酰胺1,随后1,4-还原所得的α,β-不饱和酯或酰胺。当使用D20代替H2O时,会分离到2,3-二氘代子宫酸酯或-酰胺4。提出了一种机制来解释这种综合。
  • Modified McFadyen–Stevens reaction for a versatile synthesis of aliphatic/aromatic aldehydes: design, optimization, and mechanistic investigations

    The traditional McFadyen–Stevens reaction requires harsh alkaline reaction conditions, thus precluding application to the synthesis of aliphatic aldehydes. Our modified McFadyen–Stevens reaction enables the transformation from the N,N-acylsulfonyl hydrazine to the corresponding aldehyde upon treatment with an imidazole–TMS imidazole combination without relying on oxidative or reductive reagents. The
    传统的McFadyen–Stevens反应需要苛刻的碱性反应条件,因此无法用于脂肪族醛的合成。经过改良的McFadyen–Stevens反应,在不依赖氧化剂或还原剂的情况下,通过咪唑–TMS咪唑组合处理,可以将N,N-酰基磺酰基肼转化为相应的醛。所得醛的降低的碱性和原位保护扩大了底物范围,以包括脂族醛,甚至包括带有α-氢原子的脂族醛。结合理论上的考虑,仔细检查特定底物的副反应 DFT的计算使人们对涉及酰基二氮烯和羟基卡宾作为合理中间体的McFadyen–Stevens反应有了机械的理解。
  • Inexpensive and rapid hydrogenation catalyst from CuSO4/CoCl2 — Chemoselective reduction of alkenes and alkynes in the presence of benzyl protecting groups
    作者:Mario Ficker、Søren W. Svenningsen、Thomas Larribeau、Jørn B. Christensen
    DOI:10.1016/j.tetlet.2018.02.026
    日期:2018.3
    The simple reduction of a number of alkenes and alkynes was performed with a typical reaction time of 20 min using a copper-cobalt catalytic system. The reduction did not cleave benzyl protecting groups which are usually vulnerable to catalytic hydrogenation reactions. The catalyst can be prepared in situ by reduction of the inexpensive precursor salts CuSO4 and CoCl2 with NaBH4. Sodium borohydride
    使用铜-钴催化系统,典型的反应时间为20分钟,可以简单地还原许多烯烃和炔烃。还原没有裂解通常易受催化氢化反应影响的苄基保护基。可以通过用NaBH 4还原廉价的前体盐CuSO 4和CoCl 2来原位制备催化剂。硼氢化钠还用作易于处理的氢源,用于催化还原。无需压力,加热或惰性气氛,并且使用萃取程序即可实现纯化/催化剂的去除,从而使该方法既简单又有效。

    DOI:10.1002/adsc.202000751
    日期:2021.1.19
    Direct hydrogen atom transfer from a photoredox‐generated Hantzsch ester radical cation to electron‐deficient alkenes has enabled the development of an efficient formal hydrogenation under mild, operationally simple conditions. The HAT‐driven mechanism is supported by experimental and computational studies. The reaction is applied to a variety of cinnamate derivatives and related structures, irrespective
