Silicon-carbon unsaturated compounds.: XLVIII. Synthesis and reactions of silicon analogs of lithium enolates

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 quantitative...

Zusammenfassung: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.
