  Novel One-Pot Synthesis for 2,5-Diaryl and 5-Aryl-pyridazin-3(2H)-ones

  摘要：

  A novel method for the synthesis of 2-phenyl-5-(o-hydroxyphenyl)-pyridazin-3(2H)-ones and 5-(o-hydroxyphenyl)-pyridazin-3(2H)-ones has been found during the reaction of 4-bromomethylcoumarins with phenylhydrazine and hydrazinehydrate, respectively, under controlled alkaline conditions.
