Syntheses of O-ethyl-S-propyl-O-(1-alkyl, phenyl-5-chloro, alkoxy-6-oxo-1H-pyridazine-4-yl) esters of dithiophosphoric acid are described. The compounds were investigated for their IR and UV spectra and for their contact and system activities as insecticides, acaricides, ovicides, fungicides and herbicides. Some of the compounds proved efficient acaricides; compound VIII also had an insecticide activity.

The cyclization of 3-N(4- and 5-benzimidazolyl and benztriazolyl)amino-2-cyano- and 2-ethoxycarbonyl-2-propenoate esters Ia, b-IVa, b under the conditions of the Gould-Jacobs reaction leads to angularly ring-fused substituted imidazo or triazolo[4,5-f] (V, VI) and [4,5-h] (VII, VIII) quinolines, respectively. The esters Vb-VIIIb have been transformed into the corresponding chloroderivatives Vc-VIIIc. 3-N(5-Benzimidazolyl and 5-benztriazolyl)amino-2-cyano-2-propenenitriles are cyclized in the presence of aluminium(III) chloride to give the aminoquinolines Vd, VId. The structure of the products has been characterized by their 1H, 13C NMR, IR, and UV spectra.

Trichloromethylsulfonyl-5-nitro-2-furaldehyde 4-X-phenylhydrazones I (X = H, CH3, Cl, CN, NO2, COOC2H5) were obtained by reacting 4-X-phenyldiazonium salts with 5-nitrofurfuryltrichloromethyl sulfone. These compounds react with diazomethane and trimethylamine to give the corresponding N-methylated derivatives and nitrilimines, respectively, the latter under elimination of trichlorosulfinic acid. The hydrazone-diaziridine tautomerism was studied by 1H, 15N, and 13C NMR methods; also the IR and UV spectra of the compounds synthesized are discussed. All hydrazones showed a very strong effect on the stimulation of mitochondria respiration and constitute a new type of SH-group uncouplers acting already in a 10-8 mol l-1 concentration.

The synthesis of O-(5-ethoxy-1-methyl-6-oxo-1H-pyridazin-4-yl), O-(5-methoxy-1-benzyl-6-oxo-1H-pyridazin-4-yl), O-(5-methylthio-1-methyl-6-oxo-1H-pyridazin-4-yl) and O-(5-methoxy-1-cyclohexyl-6-oxo-1H-pyridazin-4-yl) esters of phosphoric, thiophosphoric and thiophosphonic acids is described. The IR and UV spectra of the synthetized compounds were measured and interpreted and their contact and systemic insecticidal, acaricidal and ovicidal activity was determined. Several of the compounds tested displayed high activity.
