 Title    Quantitative Structure Activity Relationships of Fungicidally Active Triazoles: Analogs and Stereoisomers of Propiconazole and Etaconazole  
 Abstract    The preparation of the four stereoisomers of propiconazole (TILT®) is described. Their inhibi­ tion of the 14a-C-demethylation of the sterol nucleus is examined and compared with the inhibi­ tion by the four stereoisomers of etaconazole (SONAX®). The quantitative structure-activity relationships (Q SAR) of substituted l,3-dioxolane-2-yl-methyltriazoles and l,3-dioxane-2-yl-methyltriazoles on in vivo fungicidal activity are investigated.

 Title    A Convenient One-Pot Synthesis of Pyrazolo[3,4-d]pyrimidines and s-Triazolo[3,4-b][l,3?5]thiadiazines  
 Abstract    The reaction of 5-am ino-3-aryl-l-phenylpyrazoles (la-d) with formaldehyde and secondary amines in boiling ethanol gave the corresponding 4-alkylaminomethyl derivatives (2a-f) and bis-(4-pyrazolyl)methane (4a,b) as byproduct. Such reaction with primary aliphatic and aro­ matic amines at room temperature afforded 1,3,5-trisubstituted (5a-h) and 1,3.5,7-tetrasubsti-tuted tetrahydropyrazolo[3,4-d]pyrimidines (8a-k) respectively in good yield. Similarily, the Mannich reaction of 5-m ercapto-3-phenyl-l,2,4-triazole (9) with secondary amines, in boiling ethanol, and primary aromatic amines, at room temperature, gave 2 -substituted aminomethyl derivatives (lOa-c) and (14a-g) respectively,while with primary aliphatic amines, p-toluidine and p-anisidine,at room temperature,and with other primary aromatic amines, in boiling etha­ nol, afforded the cyclized products l,2,4-triazolo[3,4-b]thiadiazines (13a-e); (15f,g) and (15a-e), respectively.

 Title    Interaction of Herbicides with Pea Chloroplasts  
 Abstract    We have studied the effect o f three herbicides viz., triazole, pyrazon and m etribuzin on total chlorophyll, carotenoids and cell protein in leaves, and PS II and PS I activity in the chloroplasts isolated from control and herbicide treated pea plants. Pyrazon and m etribuzin at 10 (iM concen­ tration affect these parameters resulting in the chlorosis o f the leaves.

 Title    Pseudohalogenometallverbindungen, LXV [1] Synthese von Tetrazolen und Triazolen über die 1,3-dipolare Cycloaddition an die Azid-Liganden von polymeren Cobalt(III)-und PalIadium(II)-Komplexen. Darstellung und Struktur von 5-TrichlormethyItetrazol Pseudohalogeno Metal Compounds, LXV [1] Synthesis of Tetrazoles and Triazoles via 1,3-Dipolar Cycloaddition to the Azido Ligands of Polymerie Cobalt(III) and Palladium(II) Complexes. Synthesis and Structure of 5-Trichloromethyltetrazole  
 Abstract    The cycloaddition of nitriles and of dimethylacetylenedicarboxylate to the azide ligand of polymeric Schiff Base cobalt(III) and phosphine palladium(II) complexes gives the corresponding tetrazolate and triazolate complexes from which the heterocycles could be cleaved by hydrogen chloride. Usually the yields are low; if the heterocycle is soluble in ether or sublimable, yields up to 30% have been obtained. Using this method the hitherto unknown 5-trichlormethyltetrazole could be prepared which was characterized by an X-ray structural analysis. Similarly, the cyclo-addition of azido(tetraphenylporphinato)cobalt(III) with nitriles, cyclohexylisocyanide and Me0 2 CC=CC0 2 Me affords the corresponding complexes with heterocyclic ligands. The prepa-ration of tetraphenylporphyrinato(tricyanmethanido)cobalt(III), (TPP)CoN-CC(CN) 2 , is reported.
