|Outline of Final Research Achievements
Unsaturated main group 14 element species, such as disilene and disilyne, have unique properties and reactivity compared with their organic analogues. The isolation of stable disilynes, one of the most recent and intriguing additions to the catalogue of unsaturated main group species, has opened the way for further studies of the differences between organic compounds and their heavy analogues. Here, we investigated the reactivity toward organometallic reagents, such as organolithium compound and N-heterocyclic carbene (NHC) with a high σ-character, leading to the new doubly-bonded silicon compounds bearing disilenide functions. Unusual O-substututed disilene derivatives were also prepared by the reaction of a disilyne with carbonyl compounds.
