PRESENCE D’UN PHOTOCATALYSEUR PRESENCE OF A PHOTOCATALYST
L’invention concerne la synthèse de molécules fluorées. Le procédé selon l’invention permet d’accéder à un grand nombre de composés aromatiques fluorés dans des conditions douces et économiques. En particulier, l’emploi de catalyseurs métalliques n’est pas requis. The invention relates to the synthesis of fluorinated molecules. The process according to the invention makes it possible to access a large number of fluorinated aromatic compounds under mild and economical conditions. In particular, the use of metal catalysts is not required.
Les molécules fluorées présentent des propriétés intéressantes, qui peuvent notamment être recherchées dans des applications dans le domaine de la science de la vie, de l’agrochimie ou dans le domaine des matériaux. Une des propriétés visées dans cette gamme de molécules est la lipophilie permettant une meilleure biodisponibilité. Ce paramètre est d’autant plus marqué lorsque le groupement fluoré, par exemple un groupement trifluorométhyle, est associé à un chalcogène. The fluorinated molecules have interesting properties, which can be particularly sought in applications in the field of life science, agrochemistry or in the field of materials. One of the targeted properties in this range of molecules is lipophilicity allowing a better bioavailability. This parameter is even more marked when the fluorinated group, for example a trifluoromethyl group, is associated with a chalcogen.
Or, l’ajout de groupements OCF3, SCF3, SeCF3 n’est pas toujours aisé. However, the addition of groups OCF 3 , SCF 3 , SeCF 3 is not always easy.
En particulier, les méthodes actuelles permettant la formation de liaisons C(sp2)- SeCF3 font appel à des métaux de transition nobles, chers et toxiques, tels que Ni ou Pd, associés à des ligands sophistiqués également onéreux (A. Tlili, E. Ismalaj, Q. Glenadel, C. Ghiazza, T. Billard, Chem. Eur. J. 2018, 24, 3659-3670.). In particular, current methods for the formation of C (sp 2 ) -SeCF 3 bonds use noble, expensive and toxic transition metals, such as Ni or Pd, combined with expensive, expensive ligands (A. Tlili, E. Ismalaj, Q. Glenadel, C. Ghiazza, T. Billard, Chem Eur, J. 2018, 24, 3659-3670.).
D’une manière surprenante, les inventeurs ont constaté que l’activation d’un photocatalyseur par la lumière permet de s’affranchir des métaux et ligands évoqués ci- dessus. Surprisingly, the inventors have found that the activation of a photocatalyst by the light makes it possible to dispense with the metals and ligands mentioned above.

Thus, the reaction is advantageously carried out in the absence of a catalyst comprising a metal, in particular Ni or Pd, and a ligand. The process according to the invention is therefore much less expensive.
Sans vouloir se limiter, les inventeurs pensent que l’activation du photocatalyseur permet de générer une espèce radical aryle par transfert mono-électronique sur le sel de diazonium.

De manière intéressante, le procédé selon l’invention peut également être mise en œuvre avec des composés de formules II portant des fonctions -COOH, -OH, -CO-NH2, -NH-CO- , qui sont pourtant les plus sensibles à des réactions secondaires. Malgré la présence de telles fonctions sur le cycle aromatique, la réaction entre le diazonium et le chalcogène reste sélective. Ainsi, une large variété de substituants du cycle aromatique peut être envisagée. Interestingly, the process according to the invention can also be carried out with compounds of formulas II carrying the functions -COOH, -OH, -CO-NH 2 , -NH-CO-, which are however the most sensitive to side reactions. Despite the presence of such functions on the aromatic ring, the reaction between diazonium and chalcogen remains selective. Thus, a wide variety of substituents of the aromatic ring can be envisaged.

Photocatalvseurs Photocatalvseurs
Tout type de photocatalyseur peut être utilisé. Any type of photocatalyst can be used.
On peut notamment citer les photocatalyseurs organiques, tels que le triphénylpyrylium, la fluoresceine, l’Eosine Y, le Rose bengal, la tétraiodofluoresceine, le rhodamine B, la rhodamine 6G, le p-tertphenyl, le 9-Mesityl-2,7,10-méthylacridinium, le 9-mesityl-2,7- diméthyl-10-phenylacridinium. There may be mentioned in particular organic photocatalysts, such as triphenylpyrylium, fluorescein, Eosin Y, Bengal rose, tetraiodofluoresceine, rhodamine B, rhodamine 6G, p-tertphenyl, 9-Mesityl-2,7, 10-methylacridinium, 9-mesityl-2,7-dimethyl-10-phenylacridinium.

= H; R2 = Et; Rhodamine B = H; R 2 = and; Rhodamine B
R = Et; R2 = H; Rhodamine 6G p-terphenyl R = and; R 2 = H; Rhodamine 6G p-terphenyl

Le composé obtenu par le procédé selon l’invention pourra être séparé du milieu réactionnel par des méthodes bien connues de l’homme du métier, comme par exemple par extraction, évaporation du solvant ou encore par précipitation et filtration. The compound obtained by the process according to the invention may be separated from the reaction medium by methods well known to those skilled in the art, such as, for example, by extraction, evaporation of the solvent or by precipitation and filtration.
Le composé pourra être par ailleurs purifié si nécessaire par des techniques bien connues de l’homme du métier, comme par recristallisation si le composé est cristallin, par distillation, par chromatographie sur colonne sur gel de silice ou encore par chromatographie liquide haute performance (HPLC). The compound may be further purified if necessary by techniques well known to those skilled in the art, such as by recrystallization if the compound is crystalline, by distillation, by column chromatography on silica gel or by high performance liquid chromatography (HPLC ).
Dans le procédé selon l’invention, la réaction entre le diazonium et le chalcogène est sélective. Elle le reste même lorsque le groupement aromatique portant le sel de diazonium est substitué. La nature du cycle aromatique ne semble pas non plus avoir d’influence sur la réaction. Le procédé selon l’invention permet ainsi d’accéder à une grande variété de molécules aromatiques substituées par un groupe chalcogène portant un groupement (CrC6)fluoroalkyle dans des conditions douces. En effet, la réaction a lieu à température ambiante. Mais bien plus intéressant, la réaction ne nécessite pas de catalyseur métallique et de ligands, rendant ainsi le procédé très avantageux sur le plan économique. In the process according to the invention, the reaction between the diazonium and the chalcogen is selective. It remains so even when the aromatic group bearing the diazonium salt is substituted. The nature of the aromatic cycle does not seem to have any influence on the reaction either. The process according to the invention thus makes it possible to access a large variety of aromatic molecules substituted by a chalcogen group bearing a (C 1 -C 6 ) fluoroalkyl group under mild conditions. Indeed, the reaction takes place at room temperature. But more interestingly, the reaction does not require metal catalyst and ligands, thus making the process very advantageous economically.

La réaction est agitée à 25 0 C pendant 10 minutes puis refroidie à -78°C. Du DCM anhydre (27 ml) est ajouté suivi par un ajout de p- toluènesulfinate de sodium (17,7 mmol, 1 , 1 équiv.). La réaction est agitée jusqu'à conversion complète du réactif actif CI-SeCF3 à -78°C (environ 15 minutes, caractérisé par un changement de couleur du jaune à incolore). Le mélange réactionnel est ensuite filtré sur un tampon de silice (rincé au DCM) et le filtrat est concentré à sec.

Exemple 2 : déviations dans les conditions opératoires de l’exemple 1 Example 2 Deviations under the Operating Conditions of Example 1
Diverses variations, par rapport aux conditions opératoires de l’exemple 1 (à savoir 3 équivalents molaires de composé de formule III pour 1 équivalent molaire de composé de formule II, 5% molaire d’Eosin Y par rapport au composé de formule II, dans un solvant qui est le DMSO, à température ambiante pendant 16 heures sous des conditions inertes et avec un éclairage à la lumière blanche) ont été testées. Elles sont rapportées, avec le résultat, dans le tableau suivant. La teneur en base ajoutée, dans certains cas, est exprimée en pourcentage molaire par rapport au composé de formule II. Various variations, with respect to the operating conditions of Example 1 (namely 3 molar equivalents of compound of formula III for 1 molar equivalent of compound of formula II, 5 mol% of Eosin Y relative to the compound of formula II, in a solvent which is DMSO, at room temperature for 16 hours under inert conditions and with white light illumination) were tested. They are reported, with the result, in the following table. The base content added, in some cases, is expressed in mole percentage relative to the compound of formula II.
Le composé II utilisé est le composé ll-a. Compound II used is compound II-a.
Le composé III utilisé est le composé NIA. The compound III used is the compound NIA.
Tableau 1 Table 1
Ces variations confirment que le photocatalyseur activé par la lumière est nécessaire à la conduite de la réaction. Pour le couple composé ll-a/composé 1111 , la teneur molaire en Eosin Y semble devoir être d’au moins 1 % molaire pour permettre des rendements satisfaisants. These variations confirm that the photocatalyst activated by light is necessary to conduct the reaction. For the ll-a / compound 1111 compound, the molar content of Eosin Y appears to be at least 1 mol% to allow satisfactory yields.
Le choix du solvant peut être large : l’ajout d’une base peut permettre d’améliorer le rendement dans certains solvants. Dans les solvants permettant à eux seuls de bons rendements, tels que le DMSO, l’ajout d’une base n’altère pas la réaction. The choice of the solvent may be wide: the addition of a base may make it possible to improve the yield in certain solvents.
