Abstract

Reduction of dichlorobis (diisopropylamino) silane and dichlorobis (cis-2, 6- dimethylpiperidino) silane by alkali metals gave the corresponding bis (diisopropylamino) silylene and bis (cis-2, 6-dimethylpiperidino) silylene, respectively. These were successfully trapped by toluene and benzene as well as by hydrosilane, olefin, and acetylene. As the first evidence for the existence of the bridged-dimer of the diaminosilylenes, we have found ...
