Trimethylstannylpyridines 1 were treated with bromopyridines 2 in the presence of catalytic amount of tetrakis(triphenylphosphine)palladium to give the corresponding bipyridines 3 in moderate to good yields. Nicotelline (6) was similarly synthesized from 2, 4-bis(trimethylstannyl)pyridine (5) and 3-bromo-pyridine (2b).
在催化量的四(三苯基膦)钯存在下,三甲基锡基吡啶1与溴吡啶2反应,以中等至良好的产率得到相应的联吡啶3。类似地,从2,4-双(三甲基锡基)吡啶5和3-溴吡啶2b可以合成尼可替林6。
