General description
已通过结合IR和NMR光谱与计算方法，研究了二异丙基氨基锂（LDA）介导的2,6-二氟吡啶在-78°C的四氢呋喃中的邻位锂化反应。已经研究了在K2CO3存在下，各种联苯酚的双三甲基甲硅烷基衍生物与2,6-二氟吡啶在N-甲基吡咯烷酮中的缩聚反应。
Application
2,6-二氟吡啶通过与甲硅烷基化的1,1,1-三(4-羟苯基)乙烷发生缩聚反应，可制备聚吡啶醚。

Lithium diisopropylamide (LDA)-mediated ortholithiations of 2-fluoropyridine and 2,6-difluoropyridine in tetrahydrofuran at -78 °C were studied using a combination of IR and NMR spectroscopic and computational methods. Rate studies show that a substrate-assisted deaggregation of LDA dimer occurs parallel to an
Multicyclic polyethers derived from 1, 1, 1-tris (4-hydroxyphenyl) ethane and 2, 6-dihalopyridines.
