2,4,6-Tri-isopropylbenzenesulphonyl hydrazones of aliphatic and alicyclic aldehydes and ketones react readily with potassium cyanide in boiling methanol solution to give the corresponding nitriles (containing one more carbon atom than the original aldehyde or ketone) in satisfactory yields. Under the same conditions, benzaldehyde 2,4,6-tri-isopropylbenzenesulphonyl hydrazone gives phenylacetonitrile
脂族和脂环族醛和酮的2,4,6-三异丙基苯磺酰基与氰化钾在沸腾的甲醇溶液中容易反应,以令人满意的收率得到相应的腈(比原始醛或酮多含一个碳原子)。在相同条件下,苯甲醛2,4,6-三异丙基苯磺酰基生成苯乙腈的产率非常低。在某些情况下,可以在羰基化合物和2,4,6-三异丙基苯磺酰肼(11a)中在甲醇溶液中原位生成芳磺酰基,从而构成腈的一锅法制备方法。
