    • A new methodology for the synthesis of a novel difunctional- and a known trifunctional initiator, i.e., 1,3-di(2-methoxy-2-propyl)-5-isopropyl benzene and 1,3,5-tri(2-methoxy-2-propyl)benzene, respectively, for the preparation of di- and tri-telechelic polyisobutylenes. The synthesis proceeds in three steps: 1) catalytic peroxidation of 1,3,5-triisopropylbenzene, 2) reduction of the peroxides to the corresponding alcohols, and 3) methylation of the alcohols. By controlling the conversion of the key peroxidation step the relative ratio of di- and tri-functional intermediates can be controlled. By the use of the 1,3-di(2-methoxy-2-propyl)-5-isopropyl-benzene, well-defined di-methoxy telechelic polyisobutylenes can be synthesized. Although the overall combined yield of the two initiators was only 14-20%, because of the low cost of the starting material, reagents used, and simple manipulations these compounds represent the most cost effective initiators to-date for the preparation of telechelic polyisobutylenes.
    • 用于合成新的双官能和已知三官能引发剂的新方法,即1,3-二(2-甲氧基-2-丙基)-5-异丙基苯和1,3,5-三(2-甲氧基 -2-丙基)苯,用于制备二 - 和三 - 遥爪聚异丁烯。 合成分三个步骤进行:1)1,3,5-三异丙基苯的催化过氧化,2)过氧化物还原成相应的醇,3)醇的甲基化。 通过控制关键过氧化步骤的转化,可以控制二官能和三官能中间体的相对比例。 通过使用1,3-二(2-甲氧基-2-丙基)-5-异丙基苯,可以合成明确定义的二甲氧基遥爪聚异丁烯。 尽管两种引发剂的总体组合产率仅为14-20%,但是由于原料成本低,使用的试剂和简单的操作,这些化合物代表了迄今为止制备遥爪聚异丁烯的成本最高的引发剂。
