Oxopropylation of 4,5-dihalopyridazin-6-ones with chloroacetone afforded the corresponding 1-(2-oxo-propyl) derivatives. Reaction of title compound with nucleophiles such as amines, alkoxides were investigated. In addition, selective reduction of 3-nitro-1-(2-oxopropyl)pyridazin-6-ones with iron/ammonium chloride in two phase solutions or zinc in acetic acid gave the corresponding 3-amino or 3-hydroxyimino
用氯丙酮对4,5-二卤代哒嗪-6-酮进行氧丙基化,得到相应的1-(2-氧代丙基)衍生物。研究了标题化合物与亲核试剂如胺,醇盐的反应。另外,在两相溶液中用氯化铁/铵或在乙酸中的锌选择性还原3-硝基-1-(2-氧丙基)吡啶并嗪-6-酮,得到相应的3-氨基或3-羟基亚氨基衍生物。
