- Abstract
- The direct sulfonylation of 4,5-dichloropyridazin-3-ones with some benzenesulfonyl chlorides in the presence of base in tetrahydrofuran gave only the corresponding N-sulfonylated product. The reaction of 2-benzenesulfonyl-4,5-dichloropyridazin-3-ones with some aliphatic amines under neutral conditions afforded 5-alkylamino-2-benzenesulfonyl-4-chloropyridazin-3-ones and/or the corresponding N-alkyl-benzenesulfonamides.
