  摘要：

  在本研究之前已知的 2,4-二硝基苯基链烷醇的唯一代表是通过多阶段工艺从苄基氯合成的 2,4-二硝基苯甲醇 [2 5]。作为早期工作的延续 [6]，我们研究了浓硫酸对 4-硝基苄基 (I) 和 13-(4-硝基苯基)乙基 OI) 醇的硝基酯的作用。已确定这些化合物与α-硝基苯基烷基甲醇的硝基酯[6]相反，在28-420°C 下在9 3 96% 硫酸中表现出自硝化反应。该反应发生在苯环的 2 位并导致形成 2,4-二硝基苯基烷基硫酸 (C)。化合物C在稀硫酸中的水解产生2,4-二硝基苄基和13-(4-二硝基苯基)乙醇0II、IV)。该过程的快速阶段显然是硝基酯 I 和 II 的水解，产生相应的醇 (A) 和硝酸。醇 A 与硫酸反应形成其酯 - 4-硝基苯基烷基硫酸 B（众所周知，4-硝基苄醇在浓硫酸中溶解后形成 4-硝基苄基硫酸 [2]）。最后，中间体芳烷基硫酸 B 在反应条件下进行硝化（30-40°，形成
