Spiro‐diazasilole (germole) adducts were observed in reactions of dilithium salts of silole and germole dianions with N , N ′‐di‐ tert ‐butylethylenediimine in THF at room temperature. A proposed mechanism of the reaction includes metallation of N , N ′‐di‐ tert ‐butylethylenediimine and the formation of an intermediate silylene or germylene. This reaction mechanism was supported by experimental data and theoretical calculations. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
