The reaction of 2-nitropentachlorobuta-1,3-diene with a variety of anilines substituted with electron-withdrawing groups generates, contrary to expectations, N-tetrachloroallylidene-N′-arylhydrazines instead of 1,1-bisaminated substitution products. The imidoyl-type chlorides are capable of undergoing nucleophilic substitution with amines or hydrides. The resulting compounds should exhibit physiological activity, especially for use in crop science.
2-硝基五氯丁-1,3-二烯与多种带有吸电子取代基的苯胺反应,出乎意料地生成N-四氯烯丙叉-N'-芳基肼,而不是1,1-双氨取代产物。这类亚胺型氯化物能够与胺或氢化物发生亲核取代反应。生成的化合物应具有生理活性,特别是在作物科学中的应用。
