文摘

Reactions of bis(acyl)trisilanes with tris(trimethylsilyl)silyllithium in THF, followed by treatment of the resulting dark red solutions with alkyl halides, gave the Si-alkylated products and tetrakis(trimethylsilyl)silane, indicating the formation of lithium acylsilenolates via Si−Li exchange. Exothermic formation of lithium acylsilenolate was demonstrated by DFT calculations on a model reaction.
