四芳基苯衍生物及三苯基吡啶的合成

Synthesis and Characterization of Functional Tetraarylbenzene Derivatives and Triphenylpyridine

从2,4,6-三苯基吡喃钅翁盐出发,通过与相应的芳基乙酸钠盐缩合及后续的pd(0)催化的suzuki偶合反应及硝基的还原反应等得到5个(官能团化)四芳基苯衍生物:溴代四苯基苯2、对甲氧基四苯基苯3、硝基四苯基苯5、胺基四苯基苯6及1,3,5-三苯基-2-吡啶基苯7.采用1H-NMR、EA、MS对化合物的结构进行了表征.对此类化合物用于构建复杂大分子体系及用为光电材料的潜力作了预测.

Tetraarylbenzene derivatives and triphenypyridine are readily available by condensation of phenylacetates with 2,4,6-triphenlypyrylium salts and undergo suzuki coupling with boronic acid or reduction the nitrol group with Fe/HCl. The application of these compounds to construction of complicate architecture and as electrooptical materials are expected.
