Description
Foreliggende oppfinnelse gjelder en fremgangsmåte for fremstilling av eventuelt substituert 3-fenoksybenzaldehyd eller en acetal derav.
Kjente fremgangsmåter for fremstilling av 3-fenoksybenzaldehyd, se eksempelvisMonatshefte fiirChemie, Wien, 67 (1935), 598-609, er kompliserte og gir vanligvis lave utbytter av aldehydet.
Det er nå funnet at 3-fenoksybenzaldehyd og
visse derivater derav lett kan oppnås i høye utbytter fra lett tilgjengelige utgangsmaterialer.
Foreliggende oppfinnelse skaffer således en fremgangsmåte for fremstilling av et eventuelt substituert 3-fenoksybenzaldehyd eller en acetal derav, hvilken fremgangsmåte omfatter å omsette et eventuelt substituert 3-brombenzaldehyd eller en acetal derav, med en aventuelt substituert fenol eller et alkalimetallsalt derav, i nærvær av et aprotisk organisk løsningsmiddel og metallisk kobber og/eller en kobberforbindelse.
Alkalimetallsaltet av fenolen er fortrinnsvis natrium- eller kaliumsaltet, idet natriumsaltet er spesielt foretrukket fordi det gir høyere selektivitet til
3-fenoksybenzaldehydet. Saltet er fortrinnsvis vannfritt siden nærvær av vann reduserer utbyttet av 3-fenoksybenzaldehyd. Det vannfrie saltet kan fremstilles ved reaksjon mellom fenolen og et alkalimetallhydroksyd fulgt av fjerning av vann som dannes som en azeotrop med toluen eller xylen. Alternativt kan fenolen omsettes med et alkalimetallalkoksyd og den dannede alkanol kan fjernes ved destillasjon.
Det aprotiske, organiske løsningsmidlet kan være et aromatisk hydrokarbon som f.eks. toluen eller de tre xylenene, en aromatisk, heterocyklisk nitrogenforbindelse som f.eks. pyridin, 2,4,6-trimetyl-pyridin, kinolin eller pyridin-N-oksyd, et dialkylamid som f.eks. dimetylformamid eller dimetylacetamid eller et sulfoksyd som f.eks. dimetylsulfoksyd eller tetrahydro-tiqfen-1,1-oksyd.Blandinger av disse løsningsmidler kan også brukes. Kobberforbindelsen kan være en kobber(II)-forbindelse som f.eks. kuprifluorid, kupriklorid, kuprioksyd eller kupri-p-klorbenzoat, eller en kobber (I)—forbindelse som f.eks. kuproklorid, kuprobromid, kuprojodid eller kuprooksyd.
3-brombenzaldehydet og fenolen eller saltet kan anvendes i ethvert molforhold og fortrinnsvis er molforholdet mellom benzaldehyd og fenol eller salt fra 0,5:1 til 2:1, spesielt fra 0,9:1 til 1,1:1. Molforholdet mellom kobberforbindelsen og 3-brombenzaldehydet er fortrinnsvis fra 1:100
til 10:100. Reakspnstemperaturen kan eksempelvis være fra 50 til 200°C, fortrinnsvis fra 100 til 150°c, og reaksjonstiden en til fem timer.
Eksempler på substituenter som kan være til
stede i 3-brombenzaldehydet eller fenolen eller alkalimetallsaltet derav er metyl- og metoksygrupper og kloratomer. Acetalen oppnås fortrinnsvis fra en dihydrisk alkohol som f.eks. etylen-glykol.
3-Fenoksybenzaldehydet kan omsettes med hydrogen-cyanid for å gi alfa-cyano-3-fenoksybenzylalkohol, eller hydrogeneres for å gi 3-fenoksybenzylalkohol to forløpere for estere som er av pyretrin-insekticid-typen.
Oppfinnelsen skal ytterligere illustreres ved de følgende eksemplene.
Eksempel 1.
Tørt kaliumfenolat (0,02 mol) ble fremstilt fra fenol (0,02 mol) og kaliumhydroksyd (0,02 mol) fulgt av fjerning av det dannede vann som en azeotrop med toluen. Fenolatet, 3-brombenzaldehyd (0,02 mol), kuproklorid (0,0005 mol) og pyridin (5 ml) ble oppvarmet under tilbakeløp i to timer.Blandingen ble opptatt i 50 ml dietyleter og eterløsningen ble vasket med vann (3x50 ml) og tørket over vannfritt natriumsulfat.GLC-analyse avslørte at 97% av 3-brombenzaldehydet var omdannet, med en selektivitet til 3-fenoksybenzaldehyd på 8 5%.Fordampning av eterløsningen og destillasjon av resten ga rent 3-fenoksybenzaldehyd som kokte ved 12 5°C ved 0,8 mm Hg, i et utbytte av 74%. 3-fenoksybenzaldehydet kunne også renses via bisulfidkomplekset.
Sammenligningsforsøk A.
Fremgangsmåten i eksempel 1 ble gjentatt med anvendelse av 3-klorbenzaldehyd. Det ble oppnådd en kompleks blanding av forbindelser som inneholdt bare ca. 10% 3-fenoksybenzaldehyd.
Eksempel 2.
Fremgangsmåten i eksempel 1 ble gjentatt med anvendelse av 3-brombenzaldehyd-etylenglykolacetal og en reaksjons-tid på 5 timer.GLC-analyse indikerte en 90%-ig omdannelse av utgangsmaterialene, med en 90%-ig selektivitet til 3-fenoksybenzaldehyd-etylenglekolacetal.
Sammenligningsforsøk B.
Eksempel 2 ble gjentatt under anvendelse av 3-klorbenzaldehyd-etylenglykolacetal. Det ble oppnådd mindre enn 5% omdannelse etter 6 timer.
Eksempler 3 til 5.
Fremgangsmåten i eksempel 1 ble gjentatt under anvendelse av tre løsningsmidler istedenfor pyridin. Tabell I angir de anvendte løsningsmidler, omdannelsene og selektiviteten til 3-fenoksybenzaldehyd.
Eksempel 6.
0,0 5 mol natriumhydroksyd og 0,0 5 mol fenol ble blandet i 75 ml av en kommersiell blanding av o-, m- og p-xylen. Det vann som ble dannet ble fjernet ved azeotrop destillasjon ved hjelp av et Dean og Stark-apparat. Suspensjonen av natriumfenolat fremstilt på denne måten ble blandet med 2 5 ml pyridin, 0,05 mol nydestillert 3-brombenzaldehyd og 0,002 5 mol kuproklorid. Blandingen ble så oppvarmet under tilbakeløp i 30 minutter.
GLC-analyse viste da at 97% av 3-brombenzaldehydet var omdannet, med en selektivitet til 3-fenoksybenzaldehyd på 97%.
Eksempel 7.
Fremgangsmåten fra eksempel 1 ble gjentatt under anvendelse av 3-brombenzaldehyd og kalium-4-metoksyfenolat. Produktet var 3-(4-metoksyfenoksy) benzaldehyd, kp. 150°C ved 0,1 mm Hg med et utbytte på 40%.
