Several new 4-alkyl- and 4-benzyl-substituted 3,3’-oxybispyridines 1 are accessible at room temperature in high yields from 3-hydrosypyridine, potassium salt derivatives 7 and 3-bromo-4-nitropyridine 1-oxide (5d), which are readily available starting materials. The reactivity of 5d depends on the solvent.
从 3-氢吡啶、钾盐衍生物 7 和 3-溴-4-硝基吡啶 1-氧化物(5d)这些容易获得的起始原料中,可以在室温下以高产率获得几种新的 4-烷基和 4-苄基取代的 3,3'-氧二吡啶 1。5d 的反应活性取决于溶剂。
