有机硅烯的合成与反应研究

硅烯（R2Si，又称硅卡宾）和卡宾具有类似的电子结构，是重要的有机硅中间体。我们在发展有机硅烯新的高效合成方法的基础上，拟开展新型有机硅烯合成极其反应化学的研究。主要研究有机硅烯的插入与加成反应，以期利用硅烯中间体发展高效的有机化合物硅化的新方法以及新型有机硅功能分子的合成，特别是共轭有机硅分子的构筑；研究共轭效应对有机硅烯及硅多重键化合物稳定性及光谱性质的影响，为发展新型有机硅试剂和功能分子打下基础。

Silylenes, isoelectronic with carbenes, are important intermediates in organosilane synthesis. On the basis of the synthetic methods for silylenes developed in our group, we plan to synthesize new type of silylenes and study their reaction chemistry. We will focus on the studies of insertion and addition reactions of silylenes and develop new methodologies for the silylation of organic molecules and synthesis of new functional organosilanes, especially conjuagted silicon multiple bonding species. In order to establish the fundamental basis for the development of new silylation reagents and silicon functional molecules,the conjugation effect afforded by organic pai systems on the stability of silylenes and siliocn multiple bonds as well as their electronic structures will be systematically investigated,
