Description
Foreliggende oppfinnelse gjelder en fremgangsmåte for fremstilling av eventuelt substituert 3-fenoksybenzaldehyd eller en acetal derav. The present invention relates to a method for the production of optionally substituted 3-phenoxybenzaldehyde or an acetal thereof.
Kjente fremgangsmåter for fremstilling av 3-fenoksybenzaldehyd, se eksempelvisMonatshefte fiirChemie, Wien, 67 (1935), 598-609, er kompliserte og gir vanligvis lave utbytter av aldehydet. Known methods for the preparation of 3-phenoxybenzaldehyde, see for example Monatshefte fiirChemie, Wien, 67 (1935), 598-609, are complicated and usually give low yields of the aldehyde.
Det er nå funnet at 3-fenoksybenzaldehyd ogIt has now been found that 3-phenoxybenzaldehyde and
visse derivater derav lett kan oppnås i høye utbytter fra lett tilgjengelige utgangsmaterialer. certain derivatives thereof can easily be obtained in high yields from readily available starting materials.
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. The present invention thus provides a method for producing an optionally substituted 3-phenoxybenzaldehyde or an acetal thereof, which method comprises reacting an optionally substituted 3-bromobenzaldehyde or an acetal thereof, with an optionally substituted phenol or an alkali metal salt thereof, in the presence of a aprotic organic solvent and metallic copper and/or a copper compound.
Alkalimetallsaltet av fenolen er fortrinnsvis natrium- eller kaliumsaltet, idet natriumsaltet er spesielt foretrukket fordi det gir høyere selektivitet til The alkali metal salt of the phenol is preferably the sodium or potassium salt, the sodium salt being particularly preferred because it gives higher selectivity to
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. The 3-phenoxybenzaldehyde. The salt is preferably anhydrous since the presence of water reduces the yield of 3-phenoxybenzaldehyde. The anhydrous salt can be prepared by reaction between the phenol and an alkali metal hydroxide followed by removal of water formed as an azeotrope with toluene or xylene. Alternatively, the phenol can be reacted with an alkali metal alkoxide and the alkanol formed can be removed by distillation.
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. The aprotic organic solvent can be an aromatic hydrocarbon such as e.g. toluene or the three xylenes, an aromatic heterocyclic nitrogen compound such as pyridine, 2,4,6-trimethyl-pyridine, quinoline or pyridine-N-oxide, a dialkylamide such as e.g. dimethylformamide or dimethylacetamide or a sulfoxide such as e.g. dimethyl sulfoxide or tetrahydro-tiqfen-1,1-oxide. Mixtures of these solvents can also be used. The copper compound can be a copper (II) compound such as e.g. cupric fluoride, cupric chloride, cupric oxide or cupric-p-chlorobenzoate, or a copper (I) compound such as e.g. cuprous chloride, cuprous bromide, cuprous iodide or cuprous oxide.
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 The 3-bromobenzaldehyde and the phenol or salt can be used in any molar ratio and preferably the molar ratio between benzaldehyde and phenol or salt is from 0.5:1 to 2:1, especially from 0.9:1 to 1.1:1. The molar ratio between the copper compound and the 3-bromobenzaldehyde is preferably from 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. to 10:100. The reaction temperature can, for example, be from 50 to 200°C, preferably from 100 to 150°C, and the reaction time one to five hours.
Eksempler på substituenter som kan være tilExamples of substituents that may exist
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. present in the 3-bromobenzaldehyde or the phenol or the alkali metal salt thereof are methyl and methoxy groups and chlorine atoms. The acetal is preferably obtained from a dihydric alcohol such as e.g. ethylene glycol.
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. The 3-phenoxybenzaldehyde can be reacted with hydrogen cyanide to give alpha-cyano-3-phenoxybenzyl alcohol, or hydrogenated to give 3-phenoxybenzyl alcohol two precursors of esters which are of the pyrethrin insecticide type.

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. Dry potassium phenolate (0.02 mol) was prepared from phenol (0.02 mol) and potassium hydroxide (0.02 mol) followed by removal of the formed water as an azeotrope with toluene. The phenolate, 3-bromobenzaldehyde (0.02 mol), cuprous chloride (0.0005 mol) and pyridine (5 mL) were heated under reflux for two hours. The mixture was taken up in 50 mL of diethyl ether and the ether solution was washed with water (3x50 mL). and dried over anhydrous sodium sulfate. GLC analysis revealed that 97% of the 3-bromobenzaldehyde was converted, with a selectivity to 3-phenoxybenzaldehyde of 85%. Evaporation of the ether solution and distillation of the residue gave pure 3-phenoxybenzaldehyde boiling at 125° C at 0.8 mm Hg, in a yield of 74%. The 3-phenoxybenzaldehyde could also be purified via the bisulphide complex.

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. The procedure in Example 1 was repeated using three solvents instead of pyridine. Table I indicates the solvents used, the conversions and the selectivity of 3-phenoxybenzaldehyde.
Eksempel 6. Example 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. 0.05 mol of sodium hydroxide and 0.05 mol of phenol were mixed in 75 ml of a commercial mixture of o-, m- and p-xylene. The water formed was removed by azeotropic distillation using a Dean and Stark apparatus. The suspension of sodium phenolate thus prepared was mixed with 25 ml of pyridine, 0.05 mol of freshly distilled 3-bromobenzaldehyde and 0.002 5 mol of cuprous chloride. The mixture was then heated under reflux for 30 minutes.
GLC-analyse viste da at 97% av 3-brombenzaldehydet var omdannet, med en selektivitet til 3-fenoksybenzaldehyd på 97%. GLC analysis then showed that 97% of the 3-bromobenzaldehyde had been converted, with a selectivity to 3-phenoxybenzaldehyde of 97%.
Eksempel 7.Example 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%. The procedure from Example 1 was repeated using 3-bromobenzaldehyde and potassium 4-methoxyphenolate. The product was 3-(4-methoxyphenoxy)benzaldehyde, b.p. 150°C at 0.1 mm Hg with a yield of 40%.
