amines readily formed quaternary ammonium salts upon treatment with iodoacetonitrile in high yields (70–96%). The latter were selectively demethylated by heating in dimethylformamide to give aminoacetonitriles in moderate to good overall yields (36–69%).
用碘乙腈处理后,N-甲基环胺很容易形成季铵盐(70-96%)。后者通过在二甲基甲酰胺中加热选择性脱甲基,得到氨基乙腈,总收率中等至良好(36-69%)。
