Abstract

A one-step selective method based on the hydrosilylation of 2,5-norbornadiene with commercially available silanes in the presence of a Pd-catalyst and bulky ligand R-MOP is developed for the synthesis of exo-isomers of silicon-containing norbornenes. This approach leads to the formation of exclusively exo-isomers. The absence of the steps of alkylation with organometallic reagents and photochemical isomerization makes the proposed approach attractive for the targeted design and synthesis of new polymeric materials with the required properties.

Exo -5-（Pentamethyldisiloxanyl）降冰片烯的立体选择性合成和复分解聚合

抽象的

为了合成含硅降冰片烯的外消旋异构体，开发了一种基于选择性的方法，该方法基于在Pd催化剂和庞大的配体R-MOP存在下2,5-降冰片二烯与市售硅烷的硅氢加成反应。这种做法导致的形成完全外切式异构体。由于没有使用有机金属试剂进行烷基化和进行光化学异构化的步骤，因此该方法对于目标设计和合成具有所需性能的新型聚合物材料具有吸引力。
