Highly Bent 1,3-Digerma-2-silaallene

Abstract

A 1,3-digerma-2-silacyclopenta-1,2-diene, that is, a 1,3-digerma-2-silaallene incorporated into a five-membered ring system, was synthesized and obtained as a stable orange solid. Owing to incorporation into a cyclic framework, the 1,3-digerma-2-silaallene moiety is highly bent, exhibiting a Si⁰ character for the central silicon moiety.

Keywords: digermacyclobutene; digermasilaallene; germanium; silicon; silylone.
