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 (CN)‐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
报道了基于二杂芳基胺的N,N-配体的双齿(见6和12),双双齿(7、10和13)到寡双齿(见11和14)的合成(表2,4和5)。在杂芳族调查过程(C N) -键的地层,对于钯催化的单-和2,6-二氯吡啶(diamination的协议1)和4,6-二氯嘧啶5与heteroaren -2-胺2并开发了嘧啶-4,6-二胺8。结果应用于“五聚体”的合成图11A - 11D和“七聚体” 14基于4,6-二取代-2- alkylpyrimidines 5和8分别。
