  叔胺的无金属好氧氧化氰化：偶氮二异丁腈（AIBN）作为唯一氰化物源

  摘要：

  据报道，有氧氧化氰化反应可合成α-氨基腈。C（sp 3）-CN键的形成是在无金属条件下通过使用偶氮二（异丁腈）作为唯一的有机氰化物源，新戊酸和乙酸钠的组合作为添加剂而实现的。

• A metal-free direct C (sp³)–H cyanation reaction with cyanobenziodoxolones

  日期：——

  A metal-free protocol of direct C(sp3)–H cyanation with cyanobenziodoxolones functioning as both cyanating reagents and oxidants was developed. Unactivated substrates, such as alkanes, ethers and tertiary amines, were thereby transformed to the corresponding nitriles in moderate to high yields. Mechanistic studies indicated that the cyanation proceeded with two potential pathways, which is highly dependent

  开发了一种无金属的直接C（sp 3）-H氰化的方案，其中氰基苯并恶恶唑烷既起着氰化剂的作用，又起氧化剂的作用。未活化的底物，例如烷烃，醚和叔胺，由此以中等至高产率转化为相应的腈。机理研究表明，氰化反应通过两个可能的途径进行，这主要取决于底物：（1）烷烃和醚的自由基情况，以及（2）叔胺的氧化情况。
• Potassium Thiocyanate as Source of Cyanide for the Oxidative α-Cyanation of Tertiary Amines

  日期：2015.3.6

  Oxidation at the sulfur of the safe-to-handle potassium thiocyanate releases cyanide units that are trapped in the presence of co-oxidized tertiary amines to form α-amino nitriles. These cyanations work in aqueous solutions and do not require a catalyst, nor do they form toxic byproducts.

  安全处理的硫氰酸钾在硫上的氧化释放出氰化物单元，该氰化物单元在存在共氧化叔胺的情况下被捕集，形成α-氨基腈。这些氰化物在水溶液中起作用，不需要催化剂，也不会形成有毒的副产物。

  NIS/TEMPO-mediated procedure for the C−C cross-coupling reaction of tertiary amines with trimethylsilyl cyanide (TMSCN) and nitroalkanes was developed. The N-Mannich base formed from the tertiary amine and NIS had a stabilizing effect on the iminium intermediate.

  AbstractThe use of iron(II) chloride as catalyst, trimethylsilyl cyanide as source of cyanide ions, and tert‐butyl hydroperoxide as oxidant enabled the conversion of aromatic, benzylic, and aliphatic tertiary amines into α‐amino nitriles under mild conditions. Chemoselective functionalization of NCH3 to NCH2CN was achieved in the presence of N‐benzyl and N‐alkyl groups. N,N‐Dialkylanilines, PhNR2, with R=Et, Bu, Bn furnished the alkyl(aryl)aminoacetonitriles PhN(R)CH2CN as the main products accompanied by α‐amino nitriles generated by ordinary α‐cyanation of the aniline PhNR2. Formation of PhN(R)CH2CN was rationalized by oxidative degradation of N,N‐dialkylanilines to N‐alkylanilines, their condensation with formaldehyde, generated by oxidation of the solvent methanol, and final trapping of the thus formed iminium ions by cyanide.magnified image
