The cross-coupling reactions of 3,6-dihalopyridazines with triaryl- or triheteroarylbismuth compounds were performed under palladium catalysis. The reaction was highly chemoselective, affording functionalized aryl- or heteroarylpyridazinyl chlorides in moderate to good yields.
3,6-二卤代哒嗪与三芳基-或三杂芳基铋化合物的交叉偶联反应在钯催化下进行。该反应具有高度化学选择性,以中等至良好的产率提供官能化的芳基-或杂芳基哒嗪基氯。
