γ‐unsaturated α‐aminonitriles by a one‐pot two‐step procedure using potassium hexacyanoferrate(II) as a cyanide source and benzoyl chloride as a promoter under catalyst‐free condition is described. The advantages of this protocol are the use of a nontoxic, nonvolatile and inexpensive cyanating agent, no use of transition metal catalysts, high yield and simple work‐up procedure.
一种有效的方法,是在不使用催化剂的条件下,以六氰合铁酸钾(II)为氰化物源,并以苯甲酰氯为促进剂,通过一锅两步程序,进行不饱和亚胺的氢氰化反应,以合成β,γ-不饱和α-氨基腈。描述。该方案的优点是使用无毒,不挥发和廉价的氰化剂,不使用过渡金属催化剂,产率高,后处理步骤简单。
