The reaction of mesitoyl- and (2-methylbenzoyl)tris(trimethylsilyl)silane with 1 equiv. of a silyllithium gave silicon analogs of lithium enolates.Hydrolysis of the lithium silenolates afforded hydrosilanes in high yields.The lithium silenolates can be readily transformed into silenes quantitatively, by treatment with a chlorosilane. Key words: Silicon; Lithium; Unsaturated compounds; Lithium enolates
