  • Gold-Nanoparticle-Catalyzed Mild Diboration and Indirect Silaboration of Alkynes without the Use of Silylboranes

    take place and the in situ formation of the Au nanoparticle-tethered silylborane. Given that the Au-catalyzed silaboration of alkynes is faster than the rates of the corresponding disilylation and diboration pathways, we were able to achieve the indirect silaboration of alkynes with good chemoselectivities (65–85 %) without the direct use of silylboranes, which are expensive and difficult to synthesize

  • Highly efficient monophosphine platinum catalysts for alkyne diboration
    作者:Rhodri Ll. Thomas、Fabio E. S. Souza、Todd B. Marder
    DOI:10.1039/b010225n
    日期:——
    Automated parallel screening using a series of in situ generated platinum(0) phosphine complexes has allowed the identification of improved catalysts for the diboration of alkynes using bis(pinacolato)diboron (B2(pin)2, pin = OCMe2CMe2O). A selection of phosphines were added to [Pt(NBE)3] (NBE = norbornene), which contains only labile mono-olefin ligands, and the activity of the resulting solutions as catalysts for the diboration of 4-CF3C6H4CCC6H4CF3-4′ 1 by B2(pin)2 was investigated by in situ GC-MS and/or NMR spectroscopy. This allowed the optimum phosphine ∶ platinum stoichiometry to be identified as 1 ∶ 1, and the large differences in catalyst activity depending on the nature of the phosphine to be quantified. The best phosphines employed in the study, PCy3 and PPh2(o-Tol) (o-Tol = C6H4Me-o), give activities orders of magnitude greater than the worst, such as P(C6F5)3 and PBut3. The monophosphine catalysts function much more efficiently than previous catalysts for a range of alkynes allowing diborations to be performed at ambient temperatures. The diboration of strained cyclic alkenes and some vinyl- and allyl-arenes proceeded well, although the catalysts were inactive for other olefinic systems examined. As a result of these studies, the isolable and stable compound [Pt(PCy3)(η2-C2H4)2] was identified as an excellent catalyst for alkyne diboration even at room temperature. p
    使用一系列原位生成的铂(0)磷烯复合物进行的自动化平行筛选,使得能够识别出使用双(匹卡醇)二硼(B2(pin)2, pin = OCMe2CMe2O)对炔烃进行双硼化的改进催化剂。选择了一些磷烯添加到仅含有可交换的单烯配体的[Pt(NBE)3](NBE = 脱氢诺尔本烯),并通过原位气相色谱-质谱(GC-MS)和/或核磁共振(NMR)光谱研究了所得溶液作为催化剂对4-CF3C6H4CCC6H4CF3-4'的双硼化反应的活性。这使得最佳的磷烯∶铂化学计量比被识别为1∶1,并且能够量化根据磷烯性质所产生的催化剂活性的大差异。在研究中使用的最佳磷烯,PCy3和PPh2(o-Tol)(o-Tol = C6H4Me-o),其活性比最差的催化剂,如P(C6F5)3和PBut3高几个数量级。单磷烯催化剂在多种炔烃中表现出比之前催化剂更高的效率,使得在常温下可以进行双硼化反应。尽管催化剂在其他烯烃系统中无活性,但在应变环烯烃和一些乙烯-和烯丙基-芳烃的双硼化中效果良好。这些研究的结果表明,分离和稳定的化合物[Pt(PCy3)(η2-C2H4)2]被识别为即使在常温下也能作为优秀的炔烃双硼化催化剂。

    DOI:10.1002/anie.201811205
    日期:2019.1.21
    The stereoselective synthesis of anti isomers of γ‐boryl‐substituted homoallylic alcohols is disclosed. (E)‐1,2‐Di(boryl)alk‐1‐enes undergo Ru‐catalyzed double‐bond transposition with control of the geometry. The in situ generated (E)‐1,2‐di(boryl)alk‐2‐enes add to aldehydes in a stereospecific manner. The alkenylboron group within the product is amenable to a variety of synthetic derivatizations.

    日期:2019.1
    An efficient, transition-metal free, and practical approach to cis-bis(boryl)alkenes from various alkynes was disclosed in the presence of a catalytic amount of K2CO3 under mild conditions. Meanwhile, tetrasubstituted alkenes and phenanthrene derivatives were readily constructed from the target diborylalkenes via Suzuki-Miyaura cross coupling.

    DOI:10.1021/ja044396g
    日期:2004.12.1
    Catalytic enantioselective hydrogenation of prochiral vinylmetallic reagents can provide an attractive alternative to hydrometalation and bismetalation of alkenes. In this contribution, the first highly enantioselective hydrogenation of vinyl boronic esters is described. The chiral reduction products are versatile intermediates for chemical synthesis.
