• Metal-free photoinduced C(sp3)–H borylation of alkanes

  日期：2020.10.29

  precious-metal catalysts for C-H bond cleavage and, as a result, display high selectivity for borylation of aromatic C(sp2)-H bonds over aliphatic C(sp3)-H bonds4. Here we report a mechanistically distinct, metal-free borylation using hydrogen atom transfer catalysis5, in which homolytic cleavage of C(sp3)-H bonds produces alkyl radicals that are borylated by direct reaction with a diboron reagent. The reaction

  硼酸及其衍生物是化学科学中最有用的试剂之一，其应用范围涵盖药物、农用化学品和功能材料。催化 CH 硼酸化是将这些和其他硼基团引入有机分子的有效方法，因为它可用于直接官能化原料化学品的 CH 键，而无需底物预活化1-3。这些反应传统上依赖贵金属催化剂进行 CH 键断裂，因此，与脂肪族 C(sp3)-H 键相比，芳族 C(sp2)-H 键的硼化显示出高选择性。在这里，我们报告了使用氢原子转移催化的机械上独特的无金属硼化反应 5，其中 C(sp3)-H 键的均裂产生的烷基自由基通过与二硼试剂直接反应而被硼化。该反应通过基于 N-烷氧基邻苯二甲酰亚胺的氧化剂和氯氢原子转移催化剂之间的紫光光诱导电子转移进行。不同寻常的是，更强的甲基 CH 键优先于较弱的二级、三级甚至苄基 CH 键被硼化。机理研究表明，高甲基选择性是形成氯自由基 - 硼酸盐复合物的结果，该复合物选择性地切割空间不受阻碍的 CH 键。通过使用光致氢原子转移策略，

  作者：Toshiyuki Kamei、Sohshi Nishino、Toyoshi Shimada

  DOI：10.1016/j.tetlet.2018.06.024

  日期：2018.7

  Herein we report a Ni-catalyzed formal hydroboration of olefins, which afforded anti-Markovnikov-type alkylboranes with B2pin2 and a stoichiometric amount of water. Formal hydrosilylation using air- and moisture-sensitive silylboranes also proceeded under optimized conditions. The reaction with trans-stilbene and D2O resulted in 1,2-H migration, which suggested that the reaction proceeded via β-hydride

  在本文中，我们报道了烯烃的Ni催化的正式硼氢化，提供了具有B 2 pin 2和化学计量的水的反马氏复合型烷基硼烷。使用对空气和湿气敏感的甲硅烷基硼烷的正式氢化硅烷化反应也在优化条件下进行。与反式二苯乙烯和D 2 O的反应导致1,2-H迁移，这表明该反应是通过β-氢化物消除和重新插入机理进行的。

  作者：Maialen Espinal-Viguri、Callum R. Woof、Ruth L. Webster

  DOI：10.1002/chem.201602818

  日期：2016.8.8

  hydroboration (HB) of alkenes and alkynes is reported. A simple change in ligand structure leads to an extensive change in catalyst activity. Reactions proceed efficiently over a wide range of challenging substrates including activated, unactivated and sterically encumbered motifs. Conditions are mild and do not require the use of reducing agents or other additives. Large excesses of borating reagent are not required

  作者：Judy Cipot、Christopher M. Vogels、Robert McDonald、Stephen A. Westcott、Mark Stradiotto

  日期：2006.12.1

  Cationic (2a,b) and formally zwitterionic (3a,b) Rh(I) and Ir(I) complexes supported by P,N-substituted indene or indenide ligands (respectively) have been employed in the selective hydroboration of substituted vinylarenes with pinacolborane (HBpin, pin = 1,2-O2C2Me4). Notably, 3a,b exhibited remarkably high, but differing, selectivities in the hydroboration of 1-phenylpropene.
