  使用含血红素的新型聚合物负载试剂进行烷基卤的亲核取代反应

  摘要：

  通过悬浮共聚反应合成了一种由氯化血红素、二乙烯基苯和2-甲基-5-乙烯基吡啶组成的新型高分子试剂。伯、仲和叔烷基卤与氯化血红素共聚物与氰化物、叠氮化物和硫氰酸根离子的取代反应得到了令人满意的产率。根据立体化学研究，该反应机理被揭示为 SNi 型。氯化血红素共聚物不仅是具有功能性的聚合物负载试剂，而且还用于将产物与反应混合物分离。

  High assay, reaction-derived decabromodiphenylethane product is prepared by feeding (i) diphenylethane or (ii) partially brominated diphenylethane having an average bromine number less than about two, or (iii) both of (i) and (ii), into the liquid confines of a reaction mixture. Such reaction mixture is (a) formed from components comprised of excess liquid bromine and aluminum-based Lewis acid bromination catalyst, and (b) maintained at one or more elevated reaction temperatures of from about 45°-90° C., and at least when elevated pressure is needed to keep a liquid state in the reaction mixture at the temperature(s) used, the reaction mixture is at such an elevated pressure, whereby ar-bromination occurs. The feeding is conducted at a rate slow enough to form high assay reaction-derived decabromodiphenylethane product, which is an effective flame retardant.

  高纯度，反应制备的十溴二苯乙烷产物是通过将（i）二苯乙烷或（ii）部分溴化的平均溴数小于约2的二苯乙烷，或者（iii）（i）和（ii）两者都投入反应混合物的液态容器中制备的。这种反应混合物由过量的液态溴和基于铝的路易斯酸溴化催化剂组成，并且在约45℃至90℃的一个或多个升高的反应温度下维持，并且至少当需要升高压力以保持反应混合物在使用的温度下处于液态时，反应混合物处于这样的升高压力下，从而发生芳基溴化反应。给料速率足够慢，以形成高纯度的反应制备的十溴二苯乙烷产物，该产物是一种有效的阻燃剂。
