Definitions

  • the present invention relates to improved processes for the preparation of N, N'-carbonyldiazoles by reacting azolide salts with phosgene and for the preparation of azolide salts,
  • N, N'-Ca bonyldiazole can be obtained if azoles are reacted with phosgene (see DE-AS 10 33 210, Chem. Ber. 96, 337 '4 (1963) and Org. Synth. Coll. Vol. IV, 201-204 (1968) and BP-A 692 476).
  • a disadvantage of all of these processes is that the adhesion of the azole used is used as a scavenger for the hydrogen chloride formed and therefore only a maximum of 50% of the azole used can be converted into the desired carbonyldiazole. This is a serious disadvantage since azoles are expensive products and therefore a large azole consumption causes high manufacturing costs. Furthermore, some of the azole hydrochlorides are obtained as a sticky precipitate which is difficult to separate from the carbonyldiazole prepared. Finally, the azole hydrochloride formed as a by-product has to be disposed of, which causes additional costs.
  • chlorotrimethylsilane is formed again, which can be used again in the reaction after purification.
  • a disadvantage of this method are the many stages of synthesis and purification as well as the chlorotrimethylsilane, which is difficult to handle due to its hygroscopic and corrosive properties.
  • a total of three auxiliaries are to be used for this N, N'-carbonyldiimidazole synthesis, namely, chlorotrimethylsilane, 1,2-diaminoethane and sodium hydroxide solution.
  • the amine, the imidazole and the solvent required for the trimethylsilylimidazole synthesis have to be dried in a complex manner.

  • phosgene for example, 0.25 to 0.60 mol of phosgene can be used per 1 mol of azolide salt of the formula (II). This amount is preferably 0.45 to 0.55 mlJ
  • Aromatic solvents such as benzene, toluene, xylenes, monochlorobenzene, dichlorobenzenes and trichlorobenzenes and ethers such as acyoliscl ⁇ e and cyclic mono- and oligoethers, for example diethyl ether, diisopropyl ether, methyl tert-butyl ether, dibmyl ether, ethylene glycol dimethyl ether, diethylene glycol triethylene glycol, are suitable as solvents ethyl ether, tetrahydrofuran, 2-methyl-tetrahydrofura ⁇ i and dioxane. Mixtures of these solvents can also be used.
  • 2-methyl-tetrahydrofuran and aromatic solvents in particular benzene, toluene, xylenes, monochlorobenzene, dichlorobenzenes and mixtures of these solvents.
  • the preferred solvents can be easily dried, e.g. by azeotropic distillation. A water content of the solvent of less than 0J% is preferred.
  • the process according to the invention can be carried out, for example, at temperatures in the range from 10 to 120 ° C. Temperatures in the range from 20 to 100 ° C. are preferred, in particular from 40 to 100 ° C.
  • the Rcak tion temperature at least so high that the N, N-carbonyldiazole of formula (I) does not precipitate during the reaction.
  • Azolide salts of the formula (II) are, for example, according to I A. Chem. Soc. 102, 4182 or EP-A 352 352.
  • these processes are cumbersome and complex because either reagents that are difficult to handle (e.g. sodium hydride or butyllithium) are required or the azolide salt has to be isolated and purified.
  • reagents that are difficult to handle e.g. sodium hydride or butyllithium
  • a particularly favorable process for the preparation of azolide salts of the formula ( ⁇ I) has also been found, the details of which are described below.
  • Azolide salts of the formula (II) which have been prepared by the process according to the invention for the preparation of azolide salts of the formula (II) are preferably used in the process according to the invention for the preparation of N, N'-carbonyl-diazoles of the formula (I).

  • N, N'-carbonyldiazoles has the advantage that the entire azole or azolide salt used is available for the formation of N, N'-caxbonyldiazole and not half of it is converted into azole hydrochloride.
  • the yields of N, N'-cafbonyldiazole are around twice as high as in the direct reaction of azoles with phosgene.

Abstract

Des N,N'-carbonyldiazoles sont produits de façon particulièrement avantageuse en faisant réagir des sels d'azolides correspondants avec du phosgène dans un composé aromatique ou dans un éther comme solvant. Les sels d'azolides sont fabriqués de préférence, selon un nouveau procédé, à partir d'un azole, lequel est mis à réagir avec un composé de formule M'R<7> ou MgR<8>Z', en présence d'un solvant.
