摘要
Three new diisothiocyanato-functionalized 2,2'-bipyridines have been synthesized in four consecutive steps. Starting from 4-amino-2-chloro- and 2-amino-6-bromopyridine, respectively, we first prepared the corresponding diamino-2,2'-bipyridines via homo-or Negishi cross-coupling reactions which were subsequently reacted with thiophosgene.
