Description
Neue Tetrahydro-s-Triazin-Derivate Die Erfindung betrifft neue Tetrahydro-s-Triazin-Derivate und ein Verfahren zu deren Herstellung.New Tetrahydro-s-Triazine Derivatives The invention relates to new tetrahydro-s-triazine derivatives and a method for their production.
Es wurde gefunden, daß man neue Triazine erhält, wenn man Verbindungen der allgemeinen Formel in der R für einen Halogenalkylrest oder einen gegebenenfalls substituierten aromatischen Rest, der auch mit heterocyclischen Resten verbunden sein oder BrUckenglieder enthalten kann, steht, mit Carbodiimiden der allgemeinen Formel R1 - N = C = N - Rl (II) in der R1 für einen gegebenenfalls substituierten aliphatischen, aromatischen oder heterocyclischen Rest steht, bei Temperaturen von -200 bis etwa 1000C umsetzt.It has been found that new triazines are obtained by using compounds of the general formula in which R represents a haloalkyl radical or an optionally substituted aromatic radical, which can also be connected to heterocyclic radicals or contain bridge members, with carbodiimides of the general formula R1 - N = C = N - Rl (II) in which R1 represents an optionally substituted aliphatic, aromatic or heterocyclic radical, at temperatures from -200 to about 1000C.
Vorzugsweise wird bei 0 bis 50°C gearbeitet, gegebenenfalls auch in Gegenwart eines inerten Verdünnungsmittels.The process is preferably carried out at 0 to 50 ° C., if appropriate also in Presence of an inert diluent.
Die erfindungsgemäß erhältlichen neuen Verbindungen entsprechen der allgemeinen Formel in der R und R1 die oben angegebene Bedeutung haben.The new compounds obtainable according to the invention correspond to the general formula in which R and R1 have the meaning given above.
Halogenalkylreste R sind zum Beispiel Kohlenwasserstoffreste mit bis zu 12 Kohlenstoffatomen, die vorzugsweise in ß-Stellung Chlor-, Brom-, Fluor- oder Jodatome tragen.Haloalkyl radicals R are, for example, hydrocarbon radicals with up to to 12 carbon atoms, which are preferably in the ß-position chlorine, bromine, fluorine or Carry iodine atoms.
Aliphatische Reste R1 sind geradkettige oder verzweigte, gesättigte oder ungesättigte Kohlenwasserstoffreste mit vorzugsweise bis zu 25 Kohlenstoffatomen, welche bis zu 2 Doppel- oder eine Dreifachbindung enthalten können, und cycloaliphatische Reste mit 5, 6, 7, 8, 10 oder 12 Kohlenstoffatomen im Ringsystem, die gegebenenfalls auch substituiert sein können durch beispielsweise Aryl- (bis zu C20 im Ringsystem, bevorzugt Phenyl- und Naphthylrest), Aroxy- (bis zu C10 im Ringsystem, bevorzugt Phenoxyrest), Alkoxy- (C16), Nitro-, Halogen-(Fluor, Chlor, Brom, Jod), Acyl- (C1,6' Phenyl), Alkylmercapto-(c.1 Arylmercapto-(Phenyl), Cyano-, Rhodano-, Carbonester-(CI12, Aryl bis C20 im Ringsystem), Carboamid-, Dialkyl-amino (C1 8) oder Acylamino (C1 6 Phenyl)-Reste, Als aromatische Reste R und R1 kommen aromatische Kohlenwasserstoffreste mit bis zu 20 Kohlenstoffatomen (vorzugsweise mit bis zu 14 Kohlenstoffatomen), insbesondere mit bis zu 10 Kohlenstoffatomen (Phenyl-, Naphthylrest) im Ringsystem in Betracht. Die aromatischen Reste R und R1 können als Substituenten beispielsweise tragen: Alkyl-, Alkyamino-, Dialkylamino-, Alkoxyreste mit bis zu 12 Kohlenstoffatomen (Alkyl, jeweils vorzugsweise mit bis zu 6 Kohlenstoffatomen, Aryl- und Aroxygruppen (vorzugsweise jedoch Phenyl, Phenoxy), desgleichen Halogen- (vorzugsweise Fluor, Chlor, Brom), -CH0, Carbonester- (aliphatische Reste C1 12 vorzugsweise C1 6 Phenyl, Benzyl), -carboamid, Alkylsulfonyl mit Alkyl C1 12 vorzugsweise C116, Arylsulfonyl, vorzugsweise Phenylsulfonyl, Sulfonester- (aliphatische Reste C112, vorzugsweise C1,6, Phenyl, Benzyl), Sulfonamid-, Acyl-, (aliphatischer Rest C2 122 vorzugsweise C2 6 Benzoyl-), Cyano-, Rhodanid-, Alkylmercapto- (vorzugsweise Phenyl) oder Acylmercapto- (aliphatischer Rest C2 12 vorzugsweise C1 6) Arylmercapto- (vorzugsweise Phenyl) oder Acylmercapto-(aliphatischer Rest C2 12 vorzugsweise r Benzoyl-)-Gruppen sowie max. 2 N02-Gruppen.Aliphatic radicals R1 are straight-chain or branched, saturated ones or unsaturated hydrocarbon radicals with preferably up to 25 carbon atoms, which can contain up to 2 double or one triple bond, and cycloaliphatic Residues with 5, 6, 7, 8, 10 or 12 carbon atoms in the ring system, which optionally can also be substituted by, for example, aryl (up to C20 in the ring system, preferably phenyl and naphthyl radical), aroxy (up to C10 in the ring system, preferred Phenoxy radical), alkoxy (C16), nitro, halogen (fluorine, chlorine, bromine, iodine), acyl (C1.6 ' Phenyl), alkyl mercapto- (c.1 aryl mercapto- (phenyl), cyano-, rhodano-, carbon ester- (CI12, Aryl to C20 in the ring system), carboamide, dialkylamino (C1 8) or acylamino (C1 6 phenyl) residues, Aromatic radicals R and R1 are aromatic Hydrocarbon radicals with up to 20 carbon atoms (preferably with up to 14 carbon atoms), especially with up to 10 carbon atoms (phenyl, naphthyl radical) in the ring system into consideration.
