Outline of Final Research Achievements

The aim of this project is development of novel synthetic method of tricyclic heteroatom-centered annulenes by intramolecular triple ring-closing metathesis. Tris(2-hexa-1,5-dieneyl)silanes and tris(1-cyclobutenyl)silanes are employed as promising precursors of silaphenalene derivatives via sequential intramolecular metathesis.
The metathesis of these compounds in the presence of various Grubbs catalysts is now in progress.
