  摘要：

  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

• Potassium Thiocyanate as Source of Cyanide for the Oxidative α-Cyanation of Tertiary Amines

  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。
