| Outline of Final Research Achievements |
We succeeded in synthesis of a silicon analog of the smallest zero-bridge bridgehead alklene, bicyclo[1.1.0]but-1(2)-ene which are stabilized by coordination of a base (N,N-dimethylaminopyridine(DMAP)). The reaction of this molecule with a Lewis and theoretical calculations suggest that a zwitterionic structure with a homocyclopropenylium cation and an anion should contribute mainly to its structural characteristics. In addition, mechanisms for formation of a 1.3-disilabicyclo[1.1.0]butane that has an inverted geometry around the bridgehead silicon atoms as well as its reactivity toward some carbonyl compounds were disclosed. We also developed an efficient route to a polycyclic polysiloxane and its facile functionalization at the bridgehead silicon atoms.
