    Carbocupration of 1-Alkynylphosphines Followed by Trapping with Electrophiles
    摘要:
    Treatment of 1-alkynylphosphine with magnesium dialkylcuprate in ether results in regio- and stereoselective syn- carbocupration. The alkenylcopper intermediate reacts with electrophile, which leads to allylation, acylation, and phosphination. The phosphination offers a new route to gem-diphosphinoalkene, an interesting phosphorus-based organic structure.

    日期:2017.8.7
    synthesis of a vast variety of heteroatom‐containing cyclobutene‐triflones [bis(trifluoromethylsulfonyl)cyclobutenes] and cyclobutenones has been developed starting from heteroatom‐substituted alkynes and a pyridinium salt (a latent Tf2C=CH2 source). This powerful methodology, involving cyclization reactions, allows for the selective preparation of oxygen‐, nitrogen‐, bromine‐, chlorine‐, iodine‐, sulfur‐

  • Rhodium-Catalyzed Reaction of 1-Alkynylphosphines with Water Yielding (<i>E</i>)-1-Alkenylphosphine Oxides
    作者:Azusa Kondoh、Hideki Yorimitsu、Koichiro Oshima
    DOI:10.1246/bcsj.81.502
    日期:2008.4.15
    Treatment of 1-alkynylphosphines with a rhodium catalyst in 1,4-dioxane/H2O at reflux provides (E)-1-alkenylphosphine oxides in good yields with perfect stereoselectivity. The reaction proceeds as follows. Oxidative addition of 1-alkynylphosphine to rhodium followed by hydrolysis yields the corresponding terminal alkyne and diphenylphosphine oxide. Rhodium-catalyzed hydrophosphinylation of the terminal alkyne then proceeds to afford (E)-1-alkenylphosphine oxide.
    将1-炔基膦与铑催化剂在1,4-二氧六烷/水的回流条件下处理,可以高选择性且高产率地制得(E)-1-烯基膦氧化物。该反应过程如下:1-炔基膦的氧化加成到铑上,随后发生水解,生成相应的末端炔和二苯基膦氧化物。然后,铑催化的末端炔的氢膦化反应继续进行,生成(E)-1-烯基膦氧化物。
  • Selective Deprotection of Me<sub>3</sub>Si-/Ph<sub>2</sub>P(O)-protected Arylalkynes: Methyl Grignard Reagent-promoted Dephosphorylation of Ph<sub>2</sub>P(O)-protected Alkynes

    日期:2014.10.5
    A Ph2P(O)-protected alkyne underwent dephosphorylation by treatment with MeMgBr in THF with Me3Si-protection untouched. The dephosphorylation followed by a transition-metal-catalyzed coupling of the resulting terminal alkyne with aryl halides was carried out in a one-pot manner to afford the desired coupling product. Selective deprotection of Me3Si-/Ph2P(O)-protected alkynes enabled facile syntheses of expanded π-systems such as cyclic phenyleneethynylenes and unsymmetrically substituted ditriazol.
    一种Ph2P(O)保护的炔烃在THF中用MeMgBr处理后发生去磷酸化,Me3Si保护未受到影响。该去磷酸化后紧接着与芳基卤化物进行的过渡金属催化偶联反应以一锅法进行,从而获得所需的偶联产物。选择性去保护Me3Si-/Ph2P(O)保护的炔烃使得扩展π系统的合成变得简便,例如环状苯乙炔和不对称取代的二三唑。

    A protecting group Ph2P(O) for terminal ethyne was newly developed. This protecting group can be introduced readily to terminal ethyne by CuI-catalyzed phosphination and subsequent oxidation with H2O2. Ph2P(O)-protected ethynes remained intact in Sonogashira coupling, and their high polarity enabled easy separation of the desired coupling product from by-products. By treatment with t-BuOK, Ph2P(O)-protected
