Pyridazine derivatives and related compounds, part 221: Synthesis, reactions, and insecticidal activity of 3-amino-5,6-diaryl-1h-pyrazolo[3,4-c] pyridazines

Starting with 3-amino-5,6-diaryl-1H-pyrazolo[3,4-c]pyridazine, the syntheses of thiourea derivatives, dithiocarbamates, ethyl carbamate, phosphoranylidene amino, and substituted acetamido derivatives are described. The products were screened for their insecticidal activity against Mucsa, domestica, and Aphid, Macrosiphum pisi. Supplemental materials are available for this article.

Pyridazine derivatives and related compounds part 10. Reactions of 3-diazopyrazolo[3,4-c]pyridazine with reactive methylene compounds and other groups

3-Diazopyrazolo[3,4-c]pyridazine was synthesized and its transformations were investigated. With reactive methylene compounds the corresponding hydrazones and condensed 1,2,4-triazines were formed. With aromatic amines and naphthols the diazo compound was converted into arylazo derivatives. The diazo compound underwent cycloaddition, reacting as a 1,4-dipole to yield cycloaddition products.

Reactions with Diazoazoles. Part IV. (1). - and -Cyclocondensation Reactions of Diazoazoles with Acyltriphenylphosphonium Methylides to Azolotriazines

Acyltriphenylphosphoniummethylides react with diazoazoles in a - or -cycloaddition reaction followed by elimination of triphenylphosphane oxide to yield azolotriazines.
