Description
Es wurde gefunden, daß man neuartige Derivate von Imidokohlensäureesterchloriden erhält, wenn man Cyansaureester der allgemeinen Formel R(OCN), in der R einen Halogenalkyl-oder einen gegebenenfalls substituierten aromatischen Rest und it eine ganze Zahl von 1 bis 4 bedeutet, mit Carbonsäureamidderivaten der allgemeinen Formel in der X für Cl, - OSOCl oder - OPOCl2 steht, R1 fur Wasserstoff, einen aliphatischen, cycloaliphatischen sowie für einen gegebenenfalls substituierten aromatischen oder araliphatischen Rest steht, R2 und R3 fur gleiche oder verschiedene aliphatische oder gegebenenfalls substituierte aromatische und araliphatische Reste stehen, im Temperaturbereich von etwa -20 bis etwa +100°C, gebebenenfalls m Anwesenhiet eines inerten organischenm Verdünnungsmittels, zu den Imidokohlensäureesterchlorid-Derivaten der allgemeinen Formel in welcher die Substituenten R, R1, R2, R3, X und it die oben angegebene Bedeutung besitzen, umsetzt.It has been found that novel derivatives of imidocarbonic acid ester chlorides are obtained if cyanate acid esters of the general formula R (OCN), in which R is a haloalkyl or an optionally substituted aromatic radical and it is an integer from 1 to 4, with carboxamide derivatives in general formula in which X stands for Cl, - OSOCl or - OPOCl2, R1 stands for hydrogen, an aliphatic, cycloaliphatic and an optionally substituted aromatic or araliphatic radical, R2 and R3 stand for identical or different aliphatic or optionally substituted aromatic and araliphatic radicals, im Temperature range from about -20 to about + 100 ° C, if necessary with the presence of an inert organic diluent, for the imidocarbonic acid ester chloride derivatives of the general formula in which the substituents R, R1, R2, R3, X and it have the meaning given above.
Halogenalkylreste R sind z. B. Kohlenwasserstoffreste mit bis zu 12 Kohlenstoffatomen, die vorzugsweise in p-Stellung mindestens ein Fluor-, Brom-, Chlor-oder Jodatom tragen. Haloalkyl radicals R are, for. B. hydrocarbon residues with up to 12 carbon atoms, which are preferably at least one fluorine, bromine, Carry chlorine or iodine atom.
Als gegebenenfalls substituierte aromatische Reste R, R1, R2., R3 kommen bevorzugt aromatische Kohlenwasserstoffreste mit bis zu 20 Kohlenstoffatomen im Ringsystem in Betracht.
