Anwendungsgebiet der Erfindung ·
Die Erfindung betrifft eine weitere Ausbildung des Gegenstandes von Patent 136 689.
Charakteristik der bekannten technischen Lösungen Gegenstand des Hauptpatents ist ein Verfahren zur Bekämpfung von Insekten und Milben, indem man die Insekten und Milben, ihren Aufenthaltsort, ihre Brutstätten oder ihr Futter mit einer insektizid oder akärizid wirksamen Menge eines entsprechenden Wirkstoffs in Kontakt bringt, das dadurch gekennzeichnet ist, daß man als Wirkstoff Phenylalkansäure-m-phenoxybenzylester der allgemeinen Formel
// RCF2X
worin der Substituent der Formel RCF2X- in m- oder p-Stellung zu dem Kohlenstoffatom steht, an das die Alkansäureestergruppe gebunden ist, und
X ein Schwefelatom, ein Sauerstoffatom, eine Sulfinylgruppe oder eine Sulfonylgruppe,
R ein Wasserstoffatom, ein Fluoratom, ein Chloratora, eine Difluormethylgruppe oder eine Trifluormethylgruppe,

R- eine Ethylgruppe, eine- n-Propylgruppe, eine Isopropylgruppe, eine tert.-Butylgruppe oder eine Isopropenylgruppe und
R_ ein Wasserstoffatom oder eine Cyanogruppe
bedeuten, oder ein optisches Isomeres einer solchen Verbindung verwendet.
Die Herstellung dieser Phenylalkansäure-m-pheno'xybenzylester erfolgt dadurch, daß man eine Verbindung der allgemeinen Formel
CH-COA
in der A ein Halogenatom bedeutet und R und R„ die oben ange gebenen Bedeutungen besitzen, mit einem m-Phenoxybenzylalkohol der allgemeinen Formel

Bei der weiteren Bearbeitung dieses Gebiets hat sich gezeigt, daß einige der im Hauptpatent beschriebenen Ester besonders insektizid und akarizid wirksam sind, wenn sie von optisch aktiven Säuren abgeleitet werden.
g des Wesens, der Erfindung
Gegenstand der Erfindung ist daher ein Verfahren zur Bekämpfung von Insekten und Milben, das dadurch gekennzeichnet ist, daß man als Wirkstoff .(+_) -alpha-Cyano-m-phenoxybenzyl-(+)-alpha-isopropyl-4-di- oder -trifluormethoxyphenylacetat verwendet.
219 673
Die hierzu benötigten optisch aktiven Wirkstoffe werden durch übliche optische Spaltung erhalten.
Durch die folgenden Beispiele wird die Erfindung weiter
erläutert.
Beispiel Ί
Optische Spaltung von alpha-Isopropy1-4-difluormethoxyphenylessigsäure
Eine warme Lösung (60 0C) von 4,96 g (-)-alpha-Phenethylamin in 20 ml wäßrigem Ethanol (60 % Ethanol) wird zu einer warmen Lösung (60 0C) von 20 g der racemischen Säure in 50 ml wäßrigem Ethanol (60 % Ethanol) gegeben, wobei mit einem Magnetrührer gerührt wird. V7ährend des langsamen Abkühlens der Lösung auf Zimmertemperatur fällt das Salz in Form einer weißen kristallinen Substanz aus. Nach Stehenlassen der Mischung über Nacht werden die Feststoffe abfiltriert, mit 1O ml wäßrigem Ethanol gewaschen und getrocknet. Man erhält so 9,5 g Substanz vom F. = 184 bis 188 0C. Der Drehwert der aus diesem Salz erhaltenen Säure beträgt /alpha/^immertemp· = + 37,1° (CHCl3, C = 1,439 g/100 ml). Zweimaliges Umkristallisieren dieses Salzes aus wäßrigem Ethanol (60 % Ethanol) führt zu weißen Nadeln vom F. = 185 bis 187 0C, und die daraus erhaltene Säure zeigt /alpha/^immertemPeratur = +40,4° (CHCl3, C = 1,353 g/100 ml.
Herstellung von (+)-älpha-Cyan-m-phenoxybenzyl-(+)-alphaisopropyl-4-difluormethoxyphenylacetat
Die nach Beispiel 1 erhaltene (+)-Säure wird nach den in den Beispielen 15 und 16 des Hauptpatents beschriebenen Arbeitsweisen in den Ester übergeführt. N^3 = 1,5432; NMR (CDCl3) delta 6,8 bis 7,5 (m, 13H, ArH), 6,43 (t, J- 74Hz, 1H, OCHF2), 6,30 und 6,23 (2S, 1H, CH-CN), 3,27 (d,.J=IOHz, 1H, CH-CH(CH3)2)
-.* - 2t
Optische Spaltung von alpha-Isopropyl-4-trifluormethöxyphenylessigsäure
Eine Mischung aus 26,2 g der raceraischen Säure und 12,1 g (-)-alpha-Phenethylamin in 2 1 wäßrigem Ethanol (60 % Ethanol) wird zum Lösen auf einem Dampfbad erwärmt und langsam auf Zimmertemperatur abkühlen gelassen. Das Salz wird abfiltriert und getrocknet. Man erhält 16,9 g Substanz vom F. = 189 bis 193 0C. Das Salz wird zweimal aus einem Liter bzw. 600 ml wäßrigem Ethanol (60 % Ethanol) umkrisallisiert, und man erhält 8,0 g Substanz vom F. = 194 bis 196 0C. Die (+)-Säure wird durch Neutralisieren des Salzes mit verdünnter Salssäure, Extrahieren mit Ether und Verdampfen des Lösungsmittels erhalten.
/alpha/£iKlinertemp· = +35,5° (CHCl3, C=6,0 g/100 ml).
Herstellung von ( + )-alpha-Cyan-m-phenoxybenzyl-( + )-alpha-• isopropyl-4-trifluormethoxyphenylacetat
Unter Verwendung der (+)-alpha-Isopropyl-4-trifluormethoxyphenylessigsäure wird nach den in den Beispielen 15 und 16 äes Hauptpatents beschriebenen.Arbeitsweisen das Produkt als blaßgelbes öl erhalten.
