Description
Verfahren zur Herstellung substituierter s-Triazin-dione Gegenstand der Erfindung sind neue s-Triazin-dione und ein Verfahren zu ihrer Herstellung. Process for the preparation of substituted s-triazine-diones article of the invention are new s-triazine-diones and a process for their preparation.
Es wurde gefunden, daß man neuartige s-Triazin-2,4-dione erhält, wenn man Verbindungen der allgemeinen Formel worin A für die gegebenenfalls substituierten restlichen Glieder eines 5- bis 7-gliedrigen heterocyclischen Ringsystems steht und worin die Methylen- bzw. Methingruppen durch bis zu max. 2 weitere Heteroatome wie X, O, S und Se ersetst sein können, welches keinen Zerewitinoff-aktiven Wasserstoff enthält und welches gegebenenfalls mit einem gegebenenfalls substituierten Benzol-oder Naphthalinring anelliert sein kann, wobei im anellierten Ringsystem maximal 2 CH-Gruppen durch N ersetzt sein können, mit mindestens 2 Mol eines gegebenenfalls substituierten Aryl-, Alkyl- oder Cycloalkylnronoisocyanate bsw. mit mindestens einem Mol eines entsprechenden Diisocyanats in Gegenwart eines tertiären Amins, gegebenenfalls in Anwesenheit eines inerten organischen Lösungsmittels im Temperaturbereich von etwa 500 C bis etwa 2500 C, gegebenenfalls unter erhöhtem Druck, umsetzt.It has been found that novel s-triazine-2,4-diones are obtained by using compounds of the general formula in which A stands for the optionally substituted remaining members of a 5- to 7-membered heterocyclic ring system and in which the methylene or methine groups can be replaced by up to a maximum of 2 further heteroatoms such as X, O, S and Se, which are not Zerewitinoff- contains active hydrogen and which can optionally be fused with an optionally substituted benzene or naphthalene ring, with a maximum of 2 CH groups in the fused ring system being able to be replaced by N, with at least 2 mol of an optionally substituted aryl, alkyl or cycloalkylnronoisocyanate, for example. with at least one mole of a corresponding diisocyanate in the presence of a tertiary amine, optionally in the presence of an inert organic solvent in the temperature range from about 500 ° C. to about 2500 ° C., optionally under elevated pressure.
Als Substituenten für A seien beispielsweise genannt: Aliphatische Reste wie geradkettige oder verzweigte Alkylgruppen mit bis zu 12, vorzugsweise bis zu 4 tohlenstoffatomen sowie gegebenenfalls ein durch niedere Alkylreste substituierter 3-7, vorzugsweise 5-6-gliedriger cycloaliphatischer Rest, ein gegebenenfalls durch Halogen (vorzugsweise Chlor, Brom) niedere Alkyl-, Alkoxy-, Alkylmercapto-, gegebenenfalls durch niederes Alkyl substituiertes Benzolsulfonyl, niedere Dialkylaminogruppen, Phenoxy-, Nitro-, Cyano-, Trthalogenmethyl- (vorzugsweise Chlor und/ oder Fluor) substituierter Phenyl- bzw. Naphthylrest, wobei A selbst durch die für den Phenyl- bzw.
