Synthesis of a Silene from 1,1-Dilithiosilole and 2-Adamantanone
摘要:
Reaction of 1,1-dilithio-1-sila-2,3,4,5-tetraphenylsilole with 2-adamantanone produces a 5-silafulvene. This represents a new method for synthesis of silenes, leading to the first example of a silapentafulvene.

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
