  • Benign Arylations of Dimethyl Itaconate via Heck-Matsuda Reaction Utilizing in-Situ Generated Palladium on Aluminum Oxide
    作者:Lauryna Matelienė née Dauksaîtė、Jan Knaup、Frank von Horsten、Xiaoting Gu、Heiko Brunner
    DOI:10.1002/ejoc.201901708
    日期:2020.1.9
    In‐situ generated palladium on aluminium oxide provides an active and efficient catalytic system for the preparation of arylmethylidene succinates using the Heck‐Matsuda reaction. Beside the monoarylation the first examples of the biarylation of these monomers will be described.
    原位生成的氧化铝上的钯为使用Heck-Matsuda反应制备芳基亚甲基琥珀酸酯提供了一种有效而有效的催化体系。除了单芳基化以外,还将描述这些单体的二芳基化的第一个实例。
  • Novel Base-Free Catalytic Wittig Reaction for the Synthesis of Highly Functionalized Alkenes
    作者:Marie-Luis Schirmer、Sven Adomeit、Anke Spannenberg、Thomas Werner
    DOI:10.1002/chem.201503744
    日期:2016.2.12
    base‐free catalytic Wittig reactions has been developed and optimized. Initially, several potential (pre)catalysts as well as different silanes as reducing agents were screened. A system based on a readily available phosphine oxide as precatalyst and trimethoxy silane as reducing agent proved to be optimal. The effect of various Brønsted acidic additives was studied. Subsequently, the reaction conditions were
    已开发并优化了一种用于无碱催化Wittig反应的高效催化剂体系。最初,筛选了几种潜在的(预)催化剂以及不同的硅​​烷作为还原剂。基于容易获得的氧化膦作为前催化剂和三甲氧基硅烷作为还原剂的体系被证明是最佳的。研究了各种布朗斯台德酸性添加剂的效果。随后,优化反应条件并确定标准反应条件。在这些条件下,对该新协议的范围进行了评估。将九种活化烯烃和33种醛转化为42种高度官能化的烯烃。值得注意的是,可以将芳族,脂族和杂芳族醛进行转化,从而以高达99%的分离产率得到所需产物,并具有良好至优异的分离度。E / Z选择性。考虑到反应混合物的复杂性以及在一个罐中并行进行的四个反应步骤,这些结果强调了该方案的显着效率。
  • Silver sequestration of halides for the activation of Pd(OAc) <sub>2</sub> catalyzed Mizoroki‐Heck reaction of 1,1 and 1,2 ‐ Disubstituted alkenes
    作者:Pronnoy G. Bangar、Priyanka R. Jawalkar、Swapnil R. Dumbre、Dharmaraj J. Patil、Suresh Iyer
    DOI:10.1002/aoc.4159
    日期:2018.3
    A ligand free catalytic system consisting of Pd(OAc)2 (cat) and stoichiometric quantities of silver salts, AgOAc or AgBF4, exhibit high efficiency in the MizorokiHeck arylation, transforming aryl iodides and 1,1 as well as 1,2 disubstituted alkenes into 1,1,2 – trisubstituted aryl alkenes in excellent yields in very short reaction times.

  • Phosphine-Catalyzed Cross-Coupling of Benzyl Halides and Fumarates
    作者:Tingting Yan、Kaki Raveendra Babu、Yong Wu、Yang Li、Yuhai Tang、Silong Xu
    DOI:10.1021/acs.orglett.1c01214
    日期:2021.6.18
    A phosphine-catalyzed olefinic cross-coupling between benzyl halides and fumarates is described, which affords trisubstituted alkenes in good yields and excellent E-selectivity under metal-free conditions. Mechanistic studies suggest a catalytic cycle involving phosphorus ylide formation, Michael addition, water-assisted hydrogen transfer, and phosphine elimination.

  • Tris(4-anisyl)phosphine as an Efficient and Practical Reagent for the Synthesis of (<i>E</i>)-2-Benzylidenesuccinates
    作者:Huanfeng Jiang、Wei Wang、Weibing Liu、Chunli Qiao
    DOI:10.1002/cjoc.201090064
    日期:2010.2
    Condensation of maleic anhydride or dimethyl maleate with benzylaldehydes controlled by tris(4‐anisyl)‐phosphine to synthesize dimethyl (E)‐2‐benzylidenesuccinates has been systematically investigated. The protocol gives the product with high stereoselectivity in moderate to good yields under mild conditions. A plausible mechanism has been proposed.
