Abstract

Lithium alkoxides of β-silylallylic alcohols underwent the Peterson elimination in DMF to give allenes. Allenes were also directly obtained by a Peterson allenation reaction from carbonyl compounds using (Z)-(1-lithio-1-alkenyl)trimethylsilanes in one pot.

Key words

alcohols - allenes - carbonyl - elimination - silicon
