Abstract

King of donor: The chelating bis(carbene) 1 enabled the synthesis of the new silyliumylidene salt 2. This salt can be dechlorinated with sodium naphthalenide to give the first cyclic siladicarbene 3, which bears a single Si⁰ atom with strikingly high basicity. The small C-Si-C angle of 89.1° and the average C-Si distance of 1.869 Å are consistent with results from theoretical calculations, which revealed that 3 is best described as a silylone.
