Description
Procédé pour la préparation d'aldéhydes non saturés La présente invention a pour objet un procédé de préparation d'aldéhydes non saturés de formule I suivante : EMI1.1 Dans les formules I, II et III, les groupes R, R. i, Rg, RS, R4, RÏs RGF R7 et R8 représentent l'hydrogène ou des restes aromatiques, hétérocycliques ou aliphatiques linéaires ou ramifiés, libres ou reliés entre eux de façon à former des cycles, saturés ou non saturés, substitués ou non par des restes aromatiques ou hétérocycliques, tandis que R'représente un reste aliphatique, alicycli- que, aromatique ou hétérocyclique pouvant tre aisément scindé, par exemple méthyle, benzyle, phényle ou furanyle. Il est à noter que R', étant éliminé lors de la réac- tion, n'a pas d'influence sur la structure du produit final et l'importance de sa nature est d'ordre secondaire. Conformément à un mode d'exécution du procédé de l'invention on chauffe, en présence d'un catalyseur comportant au moins 7 atomes de carbone et de préfé- rence, au plus 25 atomes de carbone. Certains de ces aldéhydes peuvent tre utilisés avan tageusement dans des compositions de parfums ou d'arômes. Le procédé, objet de l'invention, consiste à condenser, en présence d'un catalyseur de cyclisation, un éther vinylique répondant à la formule générale II avec un alcool allylique répondant à la formule III : EMI1.2 de condensation, l'alcool allylique substitué III avec l'éther vinylique substitué II, à des températures comprises entre 40 et 160 mais de préférence au voisinage de 100 pendant une période dépendant de la réactivité des matières de départ, laquelle est généralement liée à la nature des substituants R à R8 selon le mode approximatif suivant : la réactivité est généralement en raison directe du pouvoir électronique répulsif des groupes RI, R3 et R4 et du pouvoir électronique attracteur des groupes Ro, RY, RS, ces pouvoirs étant évalués selon les règles usuelles. Comme catalyseur, on peut utiliser des sels de métaux ayant la propriété de former des complexes d'addition avec les oléfines tels, par exemple, de métaux appartenant à la 4e, 5e ou 6e période des éléments, comme le cobalt, l'argent ou le mercure. Suivant un mode d'exécution du procédé de l'inven- tion, on chauffe en présence d'acétate mercurique, par exemple l'éther 2-méthylbutadiényl éthylique (II, R, = CH"Rz = Ro = R4 = H et R = GH-,) avec, comme alcool allylique III, l'alcool crotylique (III, R = R5 = RG = R ; = H, R = CH3). On obtient dans ce cas le 2-mé- thyloctadien- (2, 6)-al- (1). Il va de soi que cet exemple n'est nullement limitatif et que d'autres éthers butadié- niques et d'autres alcools allyliques se prtent également au procédé suivant l'invention. L'exemple qui suit illustre la mise en oeuvre de l'invention. Exemple : Préparation du 2-méthyloctadien- (2, 6)-al- (I) Sous protection d'azote, on chauffe 17 h à 100 un mélange d'alcool crotylique (20 g), d'éther 2-méthylbuta diényl éthylique (50g), d'acétate mercurique (6,6g) et d'acétate de sodium (2,7g). Après refroidissement on ajoute du carbonate de potassium anhydre (5g), agite vigoureusement et filtre. On distille le filtrat et recueille la fraction passant à 78-80 /10 Torr. On obtient ainsi un rendement de 40 ouzo de 2-méthyloctadien-(2, 6)-al-(1) presque pur selon l'analyse par chromatographie en phase gazeuse. Par les méthodes habituelles on prépare facilement les dérivés suivants : dinitrophénylhydrazone, F. 139-1400, semicarbazone, F. 153-1550.
