  摘要：

  据报道，在1，3-二甲基咪唑-2-亚烷基硼烷（diMeImd-BH3）存在下，仲脂肪族腈的脱氰作用和丙二腈的2倍脱氰作用生成烷烃。这些反应通过自由基机理进行，该自由基机理包括向腈中加入硼烷自由基以形成亚氨基自由基，然后裂解碳-碳键。理论计算表明，这些亚胺基的β-裂解是该反应中决定速率的步骤，该裂解提供了NHC-BH2CN和相应的烷基。

  Regiospecific Decarboxylative Allylation of Nitriles

  摘要：

  Palladium-catalyzed decarboxylative alpha-allylation of nitriles readily occurs with use of Pd-2(dba)(3) and rac-BINAP. This catalyst mixture also allows the highly regiospecific alpha-allylation of nitrites in the presence of much more acidic (x-protons. Thus, the reported method provides access to compounds that are not readily available via base-mediated allylation chemistries. Lastly, mechanistic investigations indicate that there is a competition between C- and N-allylation of an intermediate nitrile-stabilized anion and that N-allylation is followed by a rapid [3,3]-sigmatropic rearrangement.

  oxyamination reaction of alkenes with ambient CO2 is reported. In the presence of I2 and DBU, CO2 is applied in situ as a protecting group to regulate the nucleophilicity of the amino group and facilitate the bicyclization of 4-pentenamines with high chemoselectivity. Moreover, this reaction provided a feasible approach to prepare prolinol carbamates with good tolerance of functional groups and high efficiency

  Radical decyanation of aliphatic nitriles was achieved in the presence of NaBH4 and a thiol. The reaction proceeds via a radical mechanism involving borane radical anion addition to nitrile to form an iminyl radical, which undergoes carbon–carbon cleavage. Reductive radical addition to acrylonitrile is followed by decyanation to give a two-carbon homologated product in a net radical ethylation reaction

  An efficient palladium‐catalyzed regioselective 5‐exo aminotrifluoromethoxylation of alkenes has been established herein, which provides a practical route towards the synthesis of OCF3‐containing pyrrolidines. tert‐Butyloxycarbonyl (Boc) as an amino protecting group plays a significant role in both the chemo‐ and regioselectivities. In addition, preliminary mechanistic studies reveal that the amino
