英文摘要: 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,
