Die vorliegende Erfindung betrifft neue Mercapto-bis-triazole, ein Verfahren zu deren Herstellung und deren Verwendung als Mikrobizide.The present invention relates to new mercapto-bis-triazoles, a process for their preparation and their use as microbicides.
Es ist bereits bekannt geworden, daß zahlreiche Bis-triazol-Derivate fungizide und an timy kotische Eigenschaften besitzen (vgl. EP-A 0 044 605 und EP-A 0 069 442). So läßt sich zum Beispiel 2-(2,4-Difluor-phenyl)-l,3-bis-(l,2,4-triazol- l-yl)-propan-2-ol zur Bekämpfung von Pilzen verwenden. Die Wirksamkeit dieses Stoffes ist gut, läßt aber bei niedrigen Aufwandmengen in manchen Fällen zu wünschen übrig.It has already become known that numerous bis-triazole derivatives have fungicidal and antimycotic properties (cf. EP-A 0 044 605 and EP-A 0 069 442). For example, 2- (2,4-difluorophenyl) -1,3-bis (1,2,4-triazol-l-yl) propan-2-ol can be used to combat fungi. The effectiveness of this substance is good, but leaves something to be desired in some cases at low application rates.

Ein Gemisch aus 1,53 g (5 mmol) 2-(2,4-Difluor-phenyl)-l,3-bis-(l,2,4-triazol-l- yl)-propan-2-ol und 30 ml absolutem Tetrahydrofuran wird bei -20°C mit 4,4 mlA mixture of 1.53 g (5 mmol) of 2- (2,4-difluorophenyl) -l, 3-bis- (l, 2,4-triazol-l-yl) propan-2-ol and 30 ml of absolute tetrahydrofuran is at -20 ° C with 4.4 ml
(11 mmol) n-Butyl-lithium in Hexan versetzt und 30 Minuten bei 0°C nachgerührt. Anschließend wird das Reaktionsgemisch auf -70°C abgekühlt, unter Rühren mit 0,19 g (6 mmol) Schwefel-Pulver versetzt, dann 1 Stunde bei -70°C und danach 2 Stunden bei 0°C gerührt. Man verdünnt das entstehende Gemisch mit Essig- säureethylester und schüttelt mehrfach mit gesättigter, wäßriger Ammonium¬ chlorid-Lösung aus. Die organische Phase wird über Natriumsulfat getrocknet und dann unter vermindertem Druck eingeengt. Das anfallende Rohprodukt (2,3 g) wird durch Chromatographie an Kieselgel mit einem Gemisch aus Ethylacetat und Ethanol = 9: 1 als Laufmittel gereinigt. Man erhält auf diese Weise 1,0 g (59 % der Theorie) an 2-(2,4-Difluor-phenyl)-l-(5-mercapto-l,2,4-triazol-l-yl)-3-(l,2,4- triazol-l-yl)-propan-2-ol in Form einer Festsubstanz vom Schmelzpunkt 187°C.(11 mmol) n-butyl lithium in hexane and stirred for 30 minutes at 0 ° C. The reaction mixture is then cooled to -70 ° C., 0.19 g (6 mmol) of sulfur powder is added with stirring, then the mixture is stirred at -70 ° C. for 1 hour and then at 0 ° C. for 2 hours. The resulting mixture is diluted with ethyl acetate and shaken out several times with saturated, aqueous ammonium chloride solution. The organic phase is dried over sodium sulfate and then concentrated under reduced pressure. The resulting crude product (2.3 g) is purified by chromatography on silica gel with a mixture of ethyl acetate and ethanol = 9: 1 as the eluent. In this way, 1.0 g (59% of theory) of 2- (2,4-difluorophenyl) -l- (5-mercapto-l, 2,4-triazol-l-yl) -3- (l, 2,4-triazol-l-yl) propan-2-ol in the form of a solid with a melting point of 187 ° C.

Lösungsmittel: 4,7 Gewichtsteile AcetonSolvent: 4.7 parts by weight of acetone
Emulgator: 0,3 Gewichtsteile Alkyl-Aryl-PolyglykoletherEmulsifier: 0.3 part by weight of alkyl aryl polyglycol ether
Zur Herstellung einer zweckmäßigen Wirkstoffzubereitung vermischt man 1 Gewichtsteil Wirkstoff mit den angegebenen Mengen Lösungsmittel und Emulgator und verdünnt das Konzentrat mit Wasser auf die gewünschte Kon¬ zentration.To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amounts of solvent and emulsifier and the concentrate is diluted with water to the desired concentration.
Zur Prüfung auf protektive Wirksamkeit werden junge Pflanzen mit der Wirkstoffzubereitung taufeucht besprüht. Nach Antrocknen des Spritzbelages werden die Pflanzen durch Bestäuben mit Konidien des Apfelmehltauerregers Podosphaera leucotricha inokuliert.To test for protective efficacy, young plants are sprayed with the preparation of active compound as moist as dew. After the spray coating has dried on, the plants are inoculated by dusting with conidia of the pod mildew pathogen Podosphaera leucotricha.
Die Pflanzen werden dann im Gewächshaus bei 23 °C und einer relativen Luft¬ feuchtigkeit von ca. 70 % aufgestellt.The plants are then placed in a greenhouse at 23 ° C. and a relative atmospheric humidity of approx. 70%.
10 Tage nach der Inokulation erfolgt die Auswertung. Dabei bedeutet 0 % einenEvaluation is carried out 10 days after the inoculation. 0% means one
Wirkungsgrad, der demjenigen der Kontrolle entspricht, während ein Wirkungs¬ grad von 100 % bedeutet, daß kein Befall beobachtet wird.Efficiency that corresponds to that of the control, while an efficiency of 100% means that no infection is observed.
