Electroreduction of nitriles gave the corresponding decyanated products when Zn was used as the material of cathode in aprotic solvent (DMF or MeCN) containing Et4NOTs as a supporting electrolyte. Alkylation of amines at the α-position was effectively achieved by cyanation of amines at the α-position, and α-alkylation of the resultant α-amino nitriles followed by the electroreductive decyanation.
当在含有Et 4 NOTs作为支持电解质的非质子传递溶剂(
DMF或MeCN)中将Zn用作阴极材料时,腈的电还原得到相应的脱
氰产物。通过使胺在α位
氰化,然后将所得的α-
氨基腈进行α-烷基化,然后进行电还原脱
氰作用,可以有效地实现α-位胺的烷基化。
