中文摘要： 本项目针对烯烃与烷氧基硅烷硅氢加成加成反应体系存在的关键基础问题，首次将含聚醚链功能化咪唑类离子液体及其相应卡宾-过渡金属配合物催化体系应用于烯烃与烷氧基硅烷硅氢加成反应。通过对功能化含聚醚链咪唑类离子液体及其相应卡宾-金属配合物中官能团的调变来提高反应转化率和加成产物的选择性；充分利用咪唑类化合物的特殊性质和空间结构特点，将官能化含聚醚链卡宾-金属配合物催化剂体系固载化，通过固载化减少功能化含聚醚链卡宾-金属配合物的用量，进一步简化反应物与催化剂的分离步骤。本研究工作，将有助于更好地解决不饱和烃与烷氧基氢硅烷硅氢加成反应中提高反应底物的转化率、加成产物的选择性以及实现催化剂体系的循环利用等问题，具有重要的理论意义和应用前景。由研究模型反应获得的规律性结果对于其它硅氢加成反应乃至其它有机硅化学合成反应也具有指导意义和借鉴价值。

英文摘要： Functionalized imidazolium based ionic liquid containing polyether chain and corresponding carbene-transition metal complexes were designed and synthesized. Then the prepared carbene-transition metal complexes were used as catalysts for hydrosilylation of alkenes with alkoxysilane. Modulating the functional groups of the functionalization imidazolium based ionic liquid containing polyether chain and its corresponding carbene-transition metal complexes, it can improve the catalytic activity of catalyst system and the selectivity of product. Because of the special nature and characteristics of spatial structure of the imidazoles compound with two attached substituent groups, immobilization of the functionalized carbene-transition metal complexes catalyst system containing polyether chain can be synthesized. And this will reduce the amount of the functionalized carbene-transition metal complexes including polyether chain; further simplify the separation step for product and catalyst. This research work will help to better solve the problems of improving the hydrosilylation reaction conversion and the selectivity of adduct as well as the realization of the catalytic system recycling which has very important theoretical meaning and application prospect. And the regularity results from research model also have guiding
