摘要
4-Chloro-5-fluoro-2-aryl-3(2H)-pyridazinones were obtained by the fluorination of 4,5-dichloro-2-aryl-3(2H)-pyridazinones with ethylhexamethylenetetramine fluoride in excellent yields. The ethylhexamethylenetetramine fluoride was synthesized by the reaction of hydrofluoric acid with ethylhexamethylenetetramine hydroxide prepared from ethylhexamethylenetetramine bromide and alkali.
