| description | Es wird ein Verfahren zur Herstellung von N,N'-Carbonyldiazolen durch Umsetzung von Azolen mit Phosgen in halogenierten aliphatischen Kohlenwasserstoffen als Lösungsmittel zur Verfügung gestellt, bei dem man die gesamte Menge des umzusetzenden Azols in dem Lösungsmittel vorlegt und anschließend Phosgen zusetzt.
Preparation of N,N'-carbonyldiazole compounds (I) comprises reacting azole compounds (II) with phosgene, where a halogenated aliphatic solvent (chlorinated, brominated or mixed chlorinated/brominated aliphatic hydrocarbon) is used and total quantity of (II) is added, followed by the addition of phosgene. Preparation of N,N'-carbonyldiazole compounds of formula (I) comprises reacting azole compounds of formula (II) with phosgene, where a halogenated aliphatic solvent (chlorinated, brominated or mixed chlorinated/brominated aliphatic hydrocarbon) is used and total quantity of (II) is added, followed by the addition of phosgene.
