    描述:
    2,4-二氯-5-溴吡啶正丁基锂四丁基氟化铵 作用下, 以 四氢呋喃乙醚正己烷 为溶剂, 反应 62.75h, 生成 4-氯-2-(二甲基氨基)吡啶

    名称:
    Regiochemically Flexible Substitutions of Di-, Tri-, and Tetrahalopyridines:  The Trialkylsilyl Trick
    摘要:
    2,4-Difluoropyridine, 2,4-dichloropyridine, 2,4,6-trifluoropyridine, 2,4,6-trichloropyridine and 2,3,4,6-tetrafluoropyridine react with standard nucleophiles exclusively at the 4-position under halogen displacement. However, the regioselectivity can be completely reversed if a trialkylsilyl group is introduced in the 5-position of the 2,4-dihalopyridines or in the 3-position of the 2,4,6-trihalopyridines or 2,3,4,6-tetrahalopyridine. Then only the halogen most remote from the bulky silyl unit (at the 2-position in the case of the 2,4-halopyridines, at the 6-position with the other substrates) gets involved in the exchange process. After removal of the silyl protective group the nucleophile is invariably found to occupy the nitrogen-neighboring position.
