Reactivity of an NHC-stabilized silylene towards ketones. Formation of silicon bis-enolates vs. bis-silylation of the C[double bond, length as m-dash]O bond.


The NHC-stabilized silylaminosilylene Ar(SiMe3)N(Cl)Si(IiPr) (, Ar = 2,6-iPr2C6H3, IiPr = 1,3-diisopropyl-4,5-dimethylimidazol-2-ylidene) reacted rapidly with a series of enolizable ketones under ambient conditions in a stereo- and regioselective fashion to afford silicon bis-enolates () in high yields with the elimination of imidazolium salt. In contrast… (More)
