tionalized 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. bipyridine - isothiocyanates - amines - thiophosgene - cross-coupling reactions
在四个连续的步骤中合成了三个新的二异硫氰酸酯官能化的2,2'-联吡啶。我们分别从4-氨基-2-氯-和2-氨基-6-溴吡啶开始,首先通过均相或Negishi交叉偶联反应制备了相应的二氨基-2,2'-联吡啶,其随后与硫光气反应。 联吡啶-异硫氰酸酯-胺-硫光气-交叉偶联反应
