Zwischenverbindungen des zweiwertigen Siliciums (Silylene)

Organosilicon Polymers?Synthesis, Architecture, Reactivity and Applications

“…118,130 As an example the reaction between dimethylsilylene and ethylene carried out in condensed phase leads to vinyldimethylsilane and also to polymeric products.…”

“…118 First, disilane 2 acts as a reservoir on the catalyst surface for the insertion of silylenes into Si-Cl bonds, which accounts for the formation of the trisilane 3. Moreover we tried to get further information about the quantum-chemical properties of the higher oligosilanes to explain the favored formation of branched silicon backbones.…”

Generation and reactions of silylenes in the gas phase

“…the silylenes, in gas phase pyrolytic reactions and also to the search for accessible sources of these molecules. 1 " 16 Recent achievements in the chemistry of gas phase reactions of silylenes, which are most interesting in the authors' view, have been correlated and systematised in the present work. 1.…”

“…1 " 16 Recent achievements in the chemistry of gas phase reactions of silylenes, which are most interesting in the authors' view, have been correlated and systematised in the present work. 1. Addition of silylenes to multiple bonds Thermal decomposition of various substituted disilanes in the gas phase is one of the most convenient and sufficiently general methods of generating silylenes.…”

“…HSiClj (1) Evidently recombination of the radical pair did not occur in this case because of the increased tendency of radical (XIII) towards intramolecular cyclisation.…”
