Model studies show that displacement of fluorine, rather than chlorine, occurs upon reaction of 3,5-dichloro-2,4,6-trifluoropyridine with sodium methoxide and phenoxide. Subsequent hydro-dechlorination can be achieved by reaction with lithium aluminium hydride whereas reaction of sodium in iso-propanol leads to formation of the tri-iso-propoxy pyridine derivative, via nucleophilic substitution of the
模型研究表明,当3,5-二氯-2,4,6-三氟吡啶与甲醇钠和酚盐反应时,会发生氟而不是氯的置换。随后的加氢脱氯化氢可通过与氢化铝锂反应来实现,而钠在异丙醇中的反应则是通过甲氧基的亲核取代而不是脱氯产物形成三异丙氧基吡啶衍生物。大环化合物可以通过适当的双官能氧亲核试剂与3,5-二氯-2,4,6-三氟吡啶的反应合成,其中一种通过X射线晶体学表征。
