α-Chlorocarbenium ions, 9, stabilized by allylic resonance, react with nitriles, 10, to give chloro substituted 2-azoniaallene salts, 12. The cation 12k abstracts chloride from the counterion SbCl6− to furnish the chloroimine 13k together with SbCl5. The hexachloroantimonates 12 can be transformed into unpolar chlorides, 13b,1, and 17, with ammonium chlorides. Compounds 13 and 17 are hydrolyzed to
通过烯丙基共振稳定的α-氯碳鎓离子9与腈10反应,生成氯取代的2-azoniaallene盐12。阳离子12K从抗衡离子的SbCl摘要氯化物6 - ,得到的氯亚胺13K与一起的SbCl 5。六氯锑酸盐12可与氯化铵转化为非极性氯化物13b,1和17。将化合物13和17水解,分别得到N-酰基亚氨基酰氯14a,b和脲基甲酸酯18。富含电子的腈插入2-氮杂苯丙烯盐12的CCl键中,得到亚氨酰氯151-p,16。
