| Summary: |
The syntheses of bidentate (see 6 and 12), bis-bidentate (7, 10, and 13) up to oligo-bidentate (see 11 and 14) diheteroarylamine-based N,N-ligands are reported (Tables 2, 4, and 5). In the course of investigations on heteroaromatic (C[BOND]N)-bond formations, a protocol for the Pd-catalyzed mono- and diamination of 2,6-dichloropyridine (1) and 4,6-dichloropyrimidines 5 with heteroaren-2-amines 2 and pyrimidine-4,6-diamines 8 is developed. The results are applied to the syntheses of the ‘pentamers’ 11a–11d and the ‘heptamer’ 14 based on 4,6-disubstituted 2-alkylpyrimidines 5 and 8, respectively.
