Popis: | Nitration of 4-alkoxy (Alk = Me, Et)-2-(1-nitro-2,3,3-trichloro-2-propenylidene)benzazetines with anhydrous HNO3 in glacial acetic acid afforded the corresponding 4-alkoxy-3-nitro-2-(1-nitro-2,3,3-trichloro-2-propenylidene)benzazetines. Reaction of compounds obtained with amines involved an isomerization of the benzazetine system into a benzazete one accompanied with conversion of the nitro compound into an aci-form. |
