The reaction of 5-methylsulfonyl-1-phenyltetrazole with pentaerythritol in acetonitrile in the presence of sodium hydroxide gave tetrakis(1-phenyltetrazol-5-yloxymethyl)methane. Sulfur-containing analog of the latter was obtained by alkylation of 1-phenyl-4,5-dihydrotetrazole-5-thione with 1,3-dibromo-2,2-bis-(bromomethyl)propane. Nitration of the resulting polytetrazoles afforded the corresponding tetrakis(p-nitrophenyl) derivatives which can be used in the synthesis of tetrazole-containing dendrimers according to the divergent scheme.
5-甲基磺酰基-1-苯基四氮唑与五羟基醇在醋腈中与氢氧化钠反应,生成四(1-苯基四氮唑-5-氧甲基)甲烷。后者的含硫类似物是通过将1-苯基-4,5-二氢四氮唑-5-硫酮与1,3-二溴-2,2-双(溴甲基)丙烷发生烷基化反应获得的。对所得多四氮唑的硝化反应可得到相应的四(对硝基苯基)衍生物,这些衍生物可根据发散合成路线用于四氮唑含量的树枝状聚合物的合成。
