Abstract
In a process for preparing aryl oligoamines, an amine is reacted with an activated aromatic and a base in a temperature range from 0 to 150° C. in the presence of a palladium component and a phosphine ligand. The aryl oligoamines are obtained simply and in good yields.
Claims12
A process for preparing aryl oligoamines, which comprises reacting an amine with an activated aromatic and a base in a temperature range from 0 to 150° C. in the presence of a palladium component and a phosphine ligand.
The process as claimed in one or more of the preceding claims, wherein a base selected from the group consisting of alkali metal and alkaline earth metal hydroxides, alkali metal and alkaline earth metal carbonates, alkali metal hydrogencarbonates, alkali metal and alkaline earth metal acetates, alkali metal and alkaline earth metal alkoxides and primary, secondary and tertiary amines is used.
The process as claimed in one or more of the preceding claims, wherein the palladium component used is palladium metal, a palladium compound or a palladium complex containing a phosphine ligand.
The process as claimed in one or more of the preceding claims, wherein a phosphine ligand selected from the group consisting of trialkylphosphines, tricycloalkylphosphines and triarylphosphines, where the three substituents on the phosphorus may be identical or different, chiral or achiral and one or more of the ligands may link the phosphorus groups of a plurality of phosphines, where part of this linkage may also be one or more metal atoms, is used.
