Acid chlorides, phosgene, thiophosgene, thionyl chloride and aromatic sulfonyl chlorides readily add to ynamines to give α-chloro-enamines. The α-chloro-β-chlorocarbonyl-enamines (V) are thermally remarkably stable as illustrated by their distillation in vacuum without decomposition. The reaction of ynamines with oxalyl chloride led to 5-disubsituted amino-2,2-dichloro-3 (2H)-furanones (XIX)
酰氯,光气,硫光气,亚硫酰氯和芳族磺酰氯很容易加到ynamines中,得到α-氯-enamines。α-氯-β-氯羰基-烯胺(V)具有热稳定性,如在真空中蒸馏而未分解所示。乙胺与草酰氯的反应生成5-二取代的氨基-2,2-二氯-3(2H)-呋喃酮(XIX)
