Rearrangements of the Phenylthio Group of Trimethylsilyl‐enolethers of α,α‐Dialkylated α‐Phenylthio‐ketones Trimethylsilyl‐enolethers of α,α‐dialkylated α‐phenylthio‐ketones undergo a photochemically induced 1,3‐phenylthio shift leading to isomeric enolethers in high yields. The rearrangement can also be carried out under thermal conditions, but the results are less satisfying.
