The isomerization of an α-trimethylsilyl ketone is lead to the corresponding trimethylsilyl enolether with the enhanced regioselectivity by heating or by the assist of trimethylsilyl trifluoromethanesulfonate. The thermal reaction discloses a new regiodefined (E)-selective route to silyl enolethers.

The rhodium catalyzed isomerization of β-trimethylsilylallyl alcohols has been successfully applied for the stepwise and selective synthesis of α-trimethylsilyl ketones and trimethylsilyl enol ethers.
Regiodefined synthesis of α-bromo, α-phenylthio, and α-phenylseleno ketones by means of specific substitution of the trimethylsilyl group in α-trimethylsilyl ketones
