Reactivity of a Silanediyl Towards Nitriles - The Role of Azasilacyclopropenes as Intermediates.

Abstract Cyclotrisilane 1a reacts with different nitriles to yield products 4–6 . the formation of which is likely to proceed via initially generated azasilacylopropenes 3a–c . Disilane 6 represents the first example of a structurally characterized pentacoordinated silyl cyanide.
