Outline of Final Research Achievements

Highly reactive, catinoic metallogermylenes and germylyne complexes were synthesized and characterized by X-ray crystal structure analysis and spectroscopy. Activation of small molecules by them have been elucidated by the experimental and computational studies. A novel cationic borylene complex was synthesized by hydride abstraction. Its unique reactivity toward diphenylacetylene has been investigated.
