Definitions

  • 1-Dimethylamino-3-dimethylimino-2-arylpropene-1-perchlorates are known to be important intermediates for the synthesis of heterocycles, e.g. Pyrimidines (see Zaschke, Z. Chem. 17 (1977) pp. 63 and 293; Arnold, Collect. Czech.
  • the present invention was therefore based on the object of making trimethine salts available which can be handled in an explosion-proof manner, in the required purity
  • trimethine salts in an aqueous medium with no acids with an oxidizing effect which can form trimethine salts which are sparingly or slightly soluble in water and which are inert towards the trimethine cation, or with
  • the invention therefore relates to explosion-proof and poorly to sparingly water-soluble trimethine salts
  • R aryl or heteroaryl, which are optionally mono- or polysubstituted by halogen, (C 1 -C 12 ) -alkyl, (C 1 -C 12 ) -alkoxy or hydroxy, aryl preferably for phenyl, naphthyl, biphenylyl, anthracenyl or Tetralinyl, and heteroaryl is preferably pyridinyl, pyrimidinyl, pyrazinyl or pyridazinyl, halogen is preferably F, Cl or Br, in particular F or Cl, and the radicals are (C 1 -C 12 ) -alkyl or
  • (C 1 -C 12 ) alkoxy are optionally mono- or polysubstituted by halogen, in particular F or Cl;
  • X an anion equivalent of a non-oxidizing and inert to the trimethine cation
  • trimethine salts preferably from the group p-toluenesulfonate, naphthalene-2-sulfonate,
  • the invention further relates to a method for
  • trimethine salts of the formula I which are sparingly soluble in water, are separated off in preferably fine-crystalline form.
  • Preferred acids of the formula III or their water-soluble salts are p-toluenesulfonic acid, p-toluenesulfonate sodium, boron tetrafluoride sodium, antimony hexafluoride sodium,
  • Naphthalene-2-sulfonic acid Naphthalene-2-sulfonic acid, naphthalene-2-sulfonate sodium, naphthalene-1-sulfonate sodium,

  • trimethine salts of the formula I prepared according to the invention are preferably obtained in fine crystalline form and
  • the solution obtained is cooled to -10 ° C. and 30 g (0.2 mol) is added to it in portions while stirring.
  • Example 1 is repeated with the modification that the clear aqueous solution obtained, instead of 38 g (0.22 mol) of sodium hexafluorophosphate, dissolved in 60 ml of water, is dissolved with 53 g (0.23 mol) of naphthalene-2-sulfonate sodium in 1.2 l of water. A light yellow immediately falls
  • Example 2 is repeated with the modification that instead of naphthalene-2-sulfonate sodium the same amount

Abstract

Fabrication de sels de triméthine antidéflagrants et peu solubles dans l'eau, de formule (I) avec: R = aryle ou hétéroaryle, le cas échéant substitués une fois ou plusieurs fois, X = équivalent anionique d'un résidu acide non oxydant et inerte par rapport à l'action du triméthine, pouvant former des sels de triméthine peu solubles dans l'eau, par formylation de composés de formule (II): R-CH2-COOH, où R a la même signification que dans la formule (I), dans les conditions de la réaction de Vilsmeier-Haack et avec une hydrolyse ultérieure du produit de formylation dans un milieu aqueux, avec formation de sels primaires de triméthine solubles dans l'eau et réaction de ces sels primaires de triméthine solubles dans l'eau dans le mélange de réaction aqueux avec des acides de formule (III): (H)nX, où X a la même notation que dans la formule (I) et n représente un nombre de 1 à 3, ou avec les sels, solubles dans l'eau, de ces acides, au moins en quantités stoechiométriques, et séparation des sels de triméthine de formule (I) peu solubles dans l'eau qui en résultent. Les sels de triméthine de formule (I) ont des applications comme produits intermédiaires pour la synthèse de composés hétérocycliques, principalement de pyrimidines et de pyridines.
