A New Type of N-Heterocyclic Silylene with Ambivalent Reactivity.

The article offers information about a study that has discovered the synthesis of the novel silylenes including heterofulvene-like stable silylene and its kinetic product, which represents two new types of metastable divalent silicon compounds with unique reactivity. Such study is undertaken due to the importance of the synthesis of isolable silylene derivatives or the molecular compounds of divalent and dicoordinate silicon in contemporary silicon chemistry.
