| Outline of Final Research Achievements |
We have successfully developed a general and moderate method to prepare functional compounds that have silicon-silicon double bonds (disilenes) from stable silyl-substituted disilenes via a selective cleavage of Si(sp2)-Si(sp3) bond. In this method, we can access functional disilenes without using strong reducing conditions that have been often used for functional disilenes. Using the developed method, we succeeded in synthesis of a variety of functional disilenes that have an polycyclic aromatic substituents and heteroatom substituents as well as tetrasila-1,3-dienes, which are conjugated disilenes, under very mild conditions and further functionalization of the resulting conjugated disilenes.
